Kim Zolciak is expanding her belly...and her brood.
The Real Housewives of Atlanta trainwreck confirmed via Twitter that she and her NFL-balling hubby, Kroy Biermann, are expecting their second child.
"@biermann71 and I are hapy to announce YES WE ARE PREGNANT!," Kim tweeted
"Kroy and I are so excited," Zolciak, 33, says. "To decide we wanted to get pregnant again and have it happen so quickly was such a blessing."
No word whether the new bundle of joy will be a boy or a girl.
Zolciak also has two daughters, 15-year-old Brielle, and 9-year-old Ariana, from a previous marriage. She met Biermann, a 26-year-old defensive end for the Atlanta Falcons, at a charity event in May 2010. The twosome tied the knot in November.
