Total Bellas star Nikki Bella issued a formal apology on Monday to the late WWF trailblazer Chyna's family after joking about her gender in a resurfaced clip from 2013. During an episode of E! series Fashion Police, the 37-year-old WWE wrestler held up a picture of Chyna and said: 'We don't know if it's a man or a woman.' 'I want to sincerely apologize for a comment I made over eight years ago on Fashion Police. I am sorry and embarrassed by my 29 year old self, who offended Chyna and, in turn, hurt her family and others,' Nikki (born Stephanie Nicole Garcia-Colace) tweeted.
