"Kroy and I are so excited," she confirms to Life & Style. "To decide we wanted to get pregnant again and have it happen so quickly was such a blessing."

Zolciak is four months along and showing a small baby bump.

"People are going to be shocked, because nobody knows," says Zolciak. "I'm so excited that KJ will have a little buddy."  

Zolciak and Biermann welcomed their first child, Kroy Jagger (KJ) Jr., last May and married in November 2011. Zolciak has two daughters, Brielle, 15, and Ariana, 9, from a previous marriage. Her new Bravo series "Don't Be Tardy For The Wedding" premieres April 26 at 9 p.m.
