Kim Zolciak wasn’t tardy for this party.

The EthermacReal Housewives of Atlanta alum shared a series of photos and videos from a recent Jelly Roll concert alongside Chet Hanks, fueling rumors her relationship with her Surreal Life costar may have turned romantic.

“One of my absolute favorite concerts and everyone that was/is part of this massive operation is beyond kind,” Kim said of the concert in a Nov. 13 Instagram post. “There are no words for the happiness and joy that surrounded us all that night.”

Kim, 46, and Chet, 34—whose parents are Tom Hanks and Rita Wilson—first met while filming the MTV reality show in Colombia, though she later confessed she was unaware of the Shameless star’s famous family.

“I had no idea who he was when I first met him to be honest,” Kim told E! News in July. “I had to call [daughter] Brielle [Biermann] and ask her.”

As for whether she and Chet might be more than friends, though, the “Tardy for the Party” singer was tight-lipped.

“I think Chet is great,” she added. “He's just a great guy and we had some very deep conversations that you'll see.”

Prior to the rumored romance, Kim was married to former NFL linebacker Kroy Biermann, with whom she shares Brielle as well as kids Ariana, 23, KJ, 13, Kash, 12, and 10-year-old twins Kaia and Kane. The former couple initially filed for divorce in May 2023 before Kim asked a judge to dismiss the case two months later; however, Kroy ultimately refiled to end the marriage that August.

Amid her marital ups and downs, Kim got candid about the painful split in a confessional on The Surreal Life.

“I protect everybody else,” she said tearfully, “and I don't feel like anybody's really protecting me, from my parents to my husband.”

She later told her costars, “The fact that I can let go here and feel safe here, not even at home, is just crazy. You know, I’ve been a mom since 18, so you gotta stay strong.”
