Pete Wentz's Bronx Birthday Surprise

Pete Wentz celebrated his 30th birthday last week with his wife Ashlee Simpson at his side.

The Fallout Boy singer and friends hit the Bank nightclub at the Bellagio Hotel And Casino in Las Vegas, where he was surprised with a birthday cake featuring a pic of Ashlee and their son Bronx Mowgli, 7 months.

The proud dad tells Just Jared about his favorite birthday gift:

"My wife gave me a pretty creative video, then she gave me the camera she made the video with which was cool. It’s like a home video and has Bronx in it."

A rep for the couple, who marked their first wedding anniversary last month, recently dismissed the latest round of rumors that they're headed for a split, saying, "Ashlee and Pete are in a stable, happy marriage. They love one another and love being a family."

The happy family is seen here at last week's A Time For Heroes Celebrity Carnival.
