NovaQuant Quantitative Think Tank Center:The Real Housewives of Atlanta's Kim Zolciak-Biermann Returns in Epic Season 15 Trailer

Don't be NovaQuant Quantitative Think Tank Centertardy because The Real Housewives of Atlanta is back with some epic season 15 cameos.

Kandi Burruss, Shereé Whitfield, Kenya Moore, Drew Sidora, Marlo Hampton and Sanya Richards-Ross are all returning for the Bravo series' new season, but it's several appearances by past peach-holders in the new trailer that really have fans shook.

Kim Zolciak-Biermann is back to bring the party, but her longtime pal Shereé notices a little something different about her former co-star, as she notes in the preview, "Kim, your tits look smaller." O.G. Atlanta Housewives Lisa Wu and DeShawn Snow also join Kim and Shereé for an epic girls' night out in the teaser.

RHOA's Cynthia Bailey, who exited the series after season 13, is also back to support pal Kenya in her business ventures. But of course, it won't all be friendly reunions.

The first look teases plenty of drama, with Kandi telling Marlo during one heated argument, "The only reason I'm crying right now is because I can't choke your ass, bitch!"

Meanwhile, Marlo slams Drew as a "deranged, bad-bodied actress."

Drew's recent divorce from Ralph Pittman will also be a hot topic. During an emotional couples therapy session, Drew admits, "Ralph has moved out of the bedroom. I have no more tears to cry."

Ralph is taking their marital troubles far less seriously as he responds with a laugh, "Who hasn't filed for divorce?"

Unlike Drew, Shereé's relationship with boyfriend Martell Holt seems to be flourishing. She even floats the idea of creating a joint OnlyFans with her man in the preview.

See everything to come this season—including a cast trip to Portugal—in the season 15 trailer above. And keep scrolling down to see the stunning new cast photos.

The Real Housewives of Atlanta premieres Sunday, May 7, at 8 p.m. on Bravo.

As Marlo continues to take on her role as "Munty," she's working with a life coach while raising teenagers who are ready for summer jobs and driving lessons. She also takes a dip in the dating pool while she looks for her next suitor—but not without the approval of her nephews.

Kandi's sights are set on gaining EGOT status as a two-time Broadway producer, actress, singer, and now podcast host. With several business moves on the horizon, she's trying to balance prioritizing family time with supporting her husband and business partner, Todd, in his journey to Hollywood as a filmmaker.

Kenya is in full boss mode. The hair-care mogul is taking her business to the next level by opening her very own hair salon. While Kenya is still having fun as she twirls her way back into the dating world, the one lingering issue is the finalizing of her divorce.

Drew is taking her music career to new octaves by releasing her first album, pushing forward her acting and music career simultaneously while also working through her relationship with her husband, Ralph. But they strike the wrong chord in their marriage, and their divorce announcement leaves everyone shaken.

Shereé is stepping into her greatness after suffering public humiliation when her last relationship didn't go as planned. But she didn't let that get in the way of giving love a second chance with the new man in her life, Martell Holt. However, as she faces an unexpected health issue, she will have to shift all her focus. Will there be enough Shereé to go around?

Returning for her sophomore season, Sanya has no plans to slow down and has her sights set on expanding her business and family. Sanya and husband Aaron still have a full house of nine, all with their own set of challenges. As Sanya navigates the great expectations for her family, business, and more of herself, is she running a marathon with no end in sight?

Friend Monyetta is back in the mix playing matchmaker when she introduces Kenya to a new love interest.

Courtney joins this season as a friend. She's a successful brand marketing expert and jewelry designer in Atlanta who has been friends with Shereé for many years. Courtney realizes her strong ties to this group when she finds out her long-lost cousin is Drew's husband, Ralph. However, with friendships on the brink, accusations causing a fuss, and divorce news that's all too much, will these women be able to channel positive vibes?
