How to Watch

Catch up on Don't Be Tardy on the Bravo App.

If you've ever wanted to see Kim Zolciak's kids pay tribute to their mom's hit song "Tardy for the Pardy," today is your lucky day.

Kim Zolciak posted an Instagram video of her sons singing her hit song—with guitars in tow. Watch it below.

"I can't with these two!! Kj and Kash I could eat you!! Don't be Tardy airing at 9/8c #newboobs," the Don’t Be Tardy star wrote on social media about the boys performing her 2009 single.

Kim's hashtag, of course, refers to some recent plastic surgery she got, which in addition to a boob job also includes a tummy tuck. "I feel so much better in a swimsuit now," she said.

Kim hasn't been shy about opening up about sculpting her body post baby. Kim gave birth to her twins, Kane and Kaia, last November. Though she admits her football-playing husband, Kroy Bierman, loves her anyway she looks.

“My husband loves me a little thicker and he loves my body—pregnant, not pregnant, flabby, not flabby," she previously told E!.

As for her kids, this isn't the first time they've showed off their pop-music bonafides. Earlier this year, Kim shared an adorable video of KJ tackling Miley Cyrus' hit "Wrecking Ball." Check it out here.
