The reality star, who was a contestant on DWTS last season, was at the studio for Monday night's episode of the hit ABC show.

The Don't Be Tardy star was spotted snapping selfies while arriving at the Los Angeles studio wearing a tight white mini dress and heels, while her daughter opted for a plunging red gown.
Zolciak-Biermann later took to Instagram to share a video herself walking her son around the set.
“KJ was suppose to come watch me dance … He never got the chance! So exciting tonight!! #DWTS #OneBigFamily,” she captioned the video.
Zolciak-Biermann had to withdraw from the competition on season 21 of DWTS after she suffered a mini stroke. Doctors then discovered a hole in her heart, and she underwent heart surgery in October.
“I was so sad. I absolutely loved Dancing with the Stars,” Zolciak-Biermann told PEOPLE in November about her ordeal. “It was the first time I'd worked outside of my home in nine years. Being able to leave my house for a day and dance in costumes, the makeup and hair, it was the time of my life. I was heartbroken having to give that up.”
Dancing with the Stars airs Mondays (8 p.m. ET) on ABC.
