It's a boy for Kristin Cavallari, Kim Zolciak

She hasn't had the baby yet, but a pal of Kristin Cavallari's fiance, Jay Cutler, spilled the beans.

Cutler's Chicago Bears teammate Earl Bennett let it slip on the Boers Bernstein sports radio show in Chicago on Tuesday. "He's having a boy," Bennett said. "I am excited for Jay. It's a great time."

And things are looking blue for reality star Kim Zolciak, 33, too.

KJ will have a best friend for life!! Thank u 4 all the Congrats!" The new boy will join baby brother KJ and sisters Brielle and Arianna.
