But says she already picked Baby Biermann's name.

Kim Zolciak and Kroy Biermann
Hold off on sending teeny blue clothes and mini footballs to the Biermann-Zolciak McMansion. Although a source claimed, "[Kim and Kroy] are so excited because Kim already had two girls and now that she's having a second son, the family will be balanced out with two of each," the Real Housewives of Atlanta's Kim Zolciak says otherwise.

"@biermann71 and I JUST found out the sex of the baby a couple days ago of and we have NOT told a soul soooo all this speculation is funny!!" Kim tweeted, shooting down rumors about K.J. getting a little brother. "I'm 4 months along and although I know the gender we just want a healthy baby!" she added. Besides, everyone knows that Kim's all-too-accurate psychic Rose already predicted this pregnancy and saw a pink nursery in the near future.

So although the baby's sex won't be a surprise to Kim, her recent cravings are another story. "I never ate a chicken wing in my life until this pregnancy now every day I dream of Pizza Huts HOT HOT wings!! I'm obsessed!" she tweeted. But perhaps the biggest shock of all will be the newborn's moniker.  "wait til u hear the new babies name ;) we came up with it all on our own ;)" the proud mama boasted. Care to guess?
