The Georgia native spoke with Bravo Insider in July 2026, where she admitted that she is super close to her sister. “My sister is my best friend,” she said. “My biggest supporter. She’s literally in my bed right now sleeping.”
Brielle, who is currently engaged to fiancé Billy Seidl, even made the trip out to NYC to support Ariana on her July 22 appearance on Watch What Happens Live with Andy Cohen, where she was sitting in the audience. “She flew into New York to see me on Watch What Happens Live, so she has supported me in anything and everything I do,” Ariana continued.

Brielle is so supportive of Ariana being a cast member on Next Gen NYC, appearing during the Season 2 premiere to attend Emira D’Spain’s birthday party with Ariana. Ariana revealed that Brielle will appear in even more episodes throughout the season. “She has filmed with me. This season, a little bit, she comes in and out a few times,” she said.
But Brielle, who made appearances with Ariana on The Real Housewives of Atlanta alongside their mom, Kim Zolciak, isn’t aiming to be a cast member on Next Gen NYC. “I don’t think this is something she’s really interested in, being personally like a full-time cast member, but she loves to be there for me in any situation,” Ariana added. “She always says like, ‘This is your thing, and I wanna support you.’ So, she’s always there to do whatever, but yeah.”
