Kim Zolciak looks good with her fifth pregnancy in a recent picture of her growing baby bump.

The mother-of-four let her fans know how well she is coming along by she posting an Instagram "selfie" on Sept. 14. She was going for a swim with her four children. The former Real Housewives of Atlanta star wore a revealing black strapless bikini with white lace trim. 

"Going swimming with the kiddos! The pool makes me feel so much lighter! This belly ... #twins #excited #blessed#nofilter," Zolciak captioned the photo of herself.

The reality star has been busy ever since she premiered her spin-off show Don't Be Tardy in the spring. She became pregnant again for the fifth time and recently moved into a custom mansion with her family, including husband Kroy Biermann.

E! News was one of the first to report on Aug. 19 news of Zolciak's pregnancy. She told the new outlet at the time, "I'm having twins and I couldn't be more excited."
