Her love affair with gene simmons. And over coming her addictions. And celebrating National Puppy day. Even the stars are showing off their lucky dogs. But first tonight, the nightline 5. And number one is comi good evening, theres an expression made famous by the feminist icon gloria steinem. A woman needs a man like a fish needs a bicycle. Some young women today are taking that sentiment to heart in dramatic fashion, by getting married to themselves. Heres abcs linsey davis. Reporter by all accounts, erica andersons wedding was perfect. I was like, on cloud 9. It was delightful. Reporter she had the wedding dress, the ring, the vows. I choose you today. I want this to be so easy. Got rose, and, yeah, had like, 20, 30 friends over. Reporter the only thing missing, the groom. I will throw the bouquet somewhere. Reporter it was all about making a formal commitment to the love of her life herself. Yeah, ive been told im a great catch and today im catching myself. Reporter what started out as a house warming, later evolved and ill marry myself. Reporter do you feel like it was an outward selfvalidation . Absolutely. Because i think its hard not to adopt whatever societys messages are, and i certainly think that one of messages is that youre not enough if youre not with someone else. Reporter but erica is far from alone. She joins a small but growing number of women from around the world, women like yasmin, who celebrated her 40th birthday by saying i do. Her mother even walked her down the aisle. Hi, its carrie bradshaw, i wanted to let you know that im getting married to myself. Reporter the notion of getting hitched solo was made popular by the show sex and the city. Think about it, if you are single after graduation, there isnt one occasion where people celebrate you. We have birthdays. Oh, no, no, no, we all have birthdays. Thats a wash. Im talking about the single gal. Reporter a pivotal scene. So, thanks, bye. Reporter that sparked the beginning of this selfloving movement. One giant step for me, one small step for single woman kind. Reporter these ceremonies are one way in which many women are embracing a modern day reality. There are more single women than ever. Roughly half of all adults in the u. S. Are married, a record low compared to the 72 of adults in 1960. Its not a legal union, you dont get any tax breaks for it or anything, its just a personal, its just a personal union. Reporter youre breaking the box entirely. Its not a cliche, and selfmarriage say radical invitation to be creative and to create your own ritual. Reporter sasha, who has been following the selfmarriage trend for more than a decade. I think it helps to deepen that commitment to selflove, which just isnt an easy thing in ourselves, where were constantly comparing ourselves on facebook. Jimm reporter she knows first happened. Her her, a selfmarriage was the perfect preparation for a future relationship. Basically, it makes you more developed as a person. Youre committed to treating yourself well. That means youre going to treat another person better too. Reporter this concept is slowly going mainstream. Dearly beloved, we are gathered today to join reporter from tv shows like glee, to this lifetime movie. And i cherish myself. Then marry yourself. Reporter called i me wed. You know, thats not such a bad idea. Reporter and the wedding industry is taking notice. The i married me kit is essential l essentially a starter kit for selfmarriages, complete with a single ring, vows and a price tag up to 240. We wanted it to be super accessible. Reporter the masterminds behind the kit were inspired by their own nuptials. They had their guests marry themselves while they said their vows. Its a starter kit. Its a template. Yeah, the idea was, i think a lot of people dont know, how would i even start, what would i do . Reporter at first, it was only available online, now its sold in their california store. Jeffrey designed the ring. Its very narrow and its very light and its very simple and that was what we decided to do, to have something delicate but super powerful. In the last three years, theyve told more than 200 kits and counting as more women embrace this tradition. Getting married here is, yeah, its everything i could have wanted. Reporter petra also chose to put a ring on it. I kept getting the question, how come youre not married, why arent you married, whats wrong with you for not being married . And i was getting a little tired of answering that question. Reporter so she took a stand. I feel like a womans chance to be wanted and worthy in our culture is actually measured in dog years. Im sorry. Were really given this little window to find a mate, find a family, have it all, before were 35. And it just isnt realistic. Reporter shes lived a successful life, a Fashion Designer by trade, even a rock star at one point, but marriage, she says, was never part of her plan. Towards the end of my 30s things started to kinda wind down, by 40, thats when i started to feel the real pressure of, gee, i missed the boat. Im thinking tool, im thinking bright colors. Reporter but she said, this is another option, asking yourself to say, i do. And while buying the ring and sketching the dress were easy i wanted to make an announcement reporter turns out, telling loved ones about her plan is proving slightly more difficult. Im getting engaged to myself. Whoa. Im getting married. I have more questions. Okay. [ laughter ] i just dont want to be i dont want you to think im sort of nut job. It doesnt hurt anyone, it doesnt take away from anyone. Youre celebrating your own relationship to yourself. Reporter validation from a friend. Perhaps the closest you get to seeking approval for your own hand in marriage. Some people say the first year is the most difficult. [ laughter ] weve had some ups and downs. These were on the stairs. Reporter as for erica anderson, shes on the verge of celebrating her oneyear anniversary. Has your relationship with yourself changed pre and post wedding ceremony . I feel like it has. In looking at my relationship to dating, because its an open marriage because youre still open to dating . Yes. So even though you are enough, and youre fulfilled alone right. Youre still willing to have someone else join your space . Yes, absolutely. Yes. But i dont have to have it. Reporter for now, she says shes happily married, and this is certainly one marriage that wont end in divorce. Someone else be so lucky to marry themselves. Reporter in new york, im linsey davis for nightline.

Katie segal first rocketed into american consciousness as the overthetop peg bundy on the hit sitcom married with children. But watching that joyous performance, you may have never guessed her painful past. Peg, what is it with you . You can change six d batteries in the dark, you cant find a twoton automobile in broad daylight. Lets not Start Talking about who cant find what in the dark. Reporter katie segal was the heart beat of married with children for 11 years. I dont shop that much. Mom, the stuff you ordered is here. Oh, goody i thought thats what all wives were like. Really . And i was going to glow up to marry somebody like you . Oh, you did not. I did. Well, she was kind of hot. Although i hope that hasnt been your situation. Lil bit. Your nose hairs look somehow longer . They moussed them. Reporter her first lead tv role, she was a rock chick. When they asked me to read for it, i thought, this is perfect for me, because this is so outside the box. We hadnt seen anything so outrageous on television before. You never bring me flowers. I would if you died. And i thought, this wont last long. Reporter that character was not supposed to be the way you ended up playing her . No, she was written very slovenly. My take on herandthat relationship between her and al bundy, there had to be something hot between the two of them to sustain the marriage for so many years. I went into the audition all dolled up. Catch a big one, al . I all right have, peg. You would be surprised how many people would call our costumer wanting her clothes, people wanted to look like her. Reporter it was the 80s. Where is the wig . Its in a big plexiglass box. People are like, do you wear it . Im like, no, i dont wear it. Reporter there so much more to katie segal than mouthy peg bundy as we discover in her memoir. Reporter theres that beautiful singing voice, which weve heard on futurama. I will always love you reporter and well soon hear again and see her in abcs 30th anniversary dirty dancing remix. Youre in the new dirty dancing. Skpngets im very dirty. I play vivian. Shes kind of the lonesome sexy diversee. This is our last night together, lover. Reporter and there was a time in her youth when kiss came to town. There was just this band of boys sitting at the table, and i was their waitress. And i sang them a song and one thing led to another, and i started this romance with gene. You say that very nonchalantly. Well, its so long ago. Reporter segals first love was music. Backing singer for bette midler . I was a harlette. I worked with her on and off for about five years. I heard bob dylan fired you . Yeah, he fired me. He fired all the singers. I was so intimidated that i knew i was singing the wrong parts. But i would never say anything. I remember the days of these skirts . I do too. This is what i wanted to do when i grow up. And this is still in there. Reporter her mum, a screen writer, her dad a director. Both of your parents died when you were young . My mother had been ill for a big part of my life. It wasnt as big a shock as my father, who i had spoken to the day before and he died on a television set. He was killed in a helicopter accident. One of the reasons i wanted to say some of this in the book, is that my way of dealing things in the moment, was to very much check out. Was to kind of anesthetize myself, numb myself. And it wasnt until i changed my lifestyle that i felt the full impact of those things. Reporter segal first took diet pills prescribed by a doctor. Learned if you feel bad, pop a pill. 15 years of booze and happy pills became a problem. I had a drug and alcohol problem that lasted through my 20s. Reporter until a chance meeting on a tv set. I met a person on a job that was sober, and she talked to me about it. Suddenly, out of nowhere popped up a lot of people that were living a life clean and sober. And i didnt really know about that. Reporter youve been clean for 30 years . Yeah. Reporter thats a massive achievement . Massive, i know. One day at a time. Reporter still . Still. What ive learned is that i can do anything for 24 hours. Reporter reasonable of course theres the bastard executioner and sons of anarchy.

To my husband, i love you. Im so glad youre the boss of me. Reporter he was the ep, she was the star. I think at a certain point, we just stop talking about work at home and dealt with our three children. Reporter had she taken early advice, this might never have happened. You were told you were not a tv person. Yeah, i met a casting director who said, you will never work in television. Reporter why . This was in the days of dynasty and dallas. When everybody on television looked extremely glamourous. I was in musicians, i was in a band. I wore a lot of black. Years later when my struggling music career was not going full steam ahead, i said yes to being in a rock musical. That led to a role on mary. Then came married with children. Sex tonight, peg . Reporter for 11 years, the secret sauce, chemistry. We loved each other instantly. Hes such an every man, downtoearth guy. Reporter now playing a slightly similar role on modern family. He has a hot wife again. I just had to throw that in. Reporter segal still acting and still making music. Reporter this summer, touring the l. A. Area with the band the reluctant apostles. Well, we want to do it in a comfortable way. Were not getting in a band. Reporter and now a slightly reluctant author. So this was a kind of book by accident . I had written pieces, just writing about my life, with the intention of giving it to my children at some point. Im pretty private, actually. But apparently not anymore. Reporter its peg bundy behind the curtain, warts and all, but dont hold your breath for a revival. It seems that all these shows are coming back in one form or another. I dont think this one will.
