By James Dinh Jan 29, 2021 Saweetie and Doja Cat's "Best Friend" is helping folks celebrate friendship and the proof is all over Instagram. Take a look at Ciara and her three-year-old daughter, Sienna, who recently shared a cute mother/daughter moment to the pair's new collaboration on Wednesday (January 27). In matching bubblegum pink-colored hair, the duo showed off some funny faces and jammed out to the rappers' hit. "That’s My Best Friend," the pop star captioned the post, tagging both the femcees and adding the hashtag #CiSi. Saweetie eventually caught wind of the dedication and showed some love to the entertainer. "My heart. I can't wait to have a baby girl," she wrote on her account.
