Kim Zolciak Shares Sexy, Makeup-Free Selfie With "Hot Ass Hubby" Kroy Biermann—See the Photo!

The 37-year-old former Real Housewives star went swimming with her family

Kim Zolciak is going makeup free! Well, she did go swimming, so it makes sense.

The 37-year-old Don't Be Tardy... star and former Real Housewives of Atlanta cast member shared on her Instagram page on Saturday a sexy selfie showing herself wearing a strapless swimsuit and cuddled up to husband and Atlanta Falcons player Kroy Biermann, 29, in a swimming pool.

"Worked this morning...took the makeup and hair off and have been swimming with my hot ass hubby and 4 little ones for hrs!" she wrote. "Does it get any better then this #IFeelFree #KroyIsSickOfTakingPicsForSnapChat."

Zolciak has flaunted her "hot ass hubby" on social media before. In April, she posted a pic showing her in a bikini, standing with him at the beach and licking his toned chest.

Zolciak and her hubby share four children—Kroy Jr., aka KJ, 4, and Kash, 2, and twins Kane and Kaia, 1.
