Kristin Cavallari and her fiance Jay Cutler are expecting a baby boy!

The couple hadn't yet revealed the sex of their baby, so Jay's Chicago Bears teammate Earl Bennett did it for them on a local Chicago radio station Tuesday and RadarOnline.com has the audio.

"A baby on the way, he's having a boy and I'm excited for Jay," Earl said on The Boers and Bernstein Show on 670 the Score.

Hilary Duff gave birth to a baby boy on Tuesday named Luca Cruz Comrie.

The 24-year-old made the official announcement on Twitter Thursday afternoon saying, "Welcome to the world Luca Cruz Comrie! Tuesday evening we became proud parents of a healthy 7 pound 6 ounce beautiful boy."

That’s one hot mama, and even daddy agrees!

Ben Affleck couldn’t keep his hands off his very pregnant wife Jennifer Garner, and RadarOnline.com has the photos of their PDA packed day.

Running errands in Santa Monica on Wednesday, Jen was all smiles when Ben (with his scruffy beard) planted smooches sweetly on her head while holding onto their daughter Violet’s hand.

The oldest of the Garner-Affleck children, Violet turns six on Thursday, and she was skipping along beside her parents in a bright yellow dress and adorable pink shoes.
