Kim Zolciak and hubby Kroy Biermann are counting down the days until their little bundles of joy enter the world, and the former Real Housewives of Atlanta star is even documenting their progress on Instagram. 

Zolciak, 35, is due to give birth later this month, and still fearlessly took to Instagram to post a picture of her bare bump. 

"Sooooo with all the request I finally decided to post My baby bump today! The twins will here this month and we are soooo excited and I'm soooo over being pregnant! #countingdownthedays," she captioned the picture

The mother of four has a right to be "over" her pregnancy. After she gives birth to these two, Zolciak will have had four children in just over two years. 

The reality star married Atlanta Falcons defensive end Kroy Biermann, 28, in November 2011, and they've since welcomed sons KJ, 2, and Kash, 1. Zolciak had daughters Brielle, 16, and Ariana, 12, from previous relationships. 

The proud mom has posted several pregnancy selfless on Instagram in the last few months, including a bikini shot in her sixth month of pregnancy.

She has said that these twins will be her last children, and so far the couple doesn't know the babies' sexes, hoping to keep it a surprise.
