"She is 100% pregnant," Zolciak's former rep and close pal Jonathan Jaxson confirms to, noting that Zolciak is about "five months" along.

The baby-to-be's dad is Atlanta Falcons defensive end Kroy Bierman, 25, whom Zolciak, 32, befriended at an Atlanta charity function earlier this year (Their first meeting was documented on a recent episode of Bravo's hit.)

As show fans know, "Tardy for the Party" singer Zolciak already has two daughters, Brielle, 13, and Ariana, 9, from two previous relationships.
