Sunday was family day for Ashlee Simpson and Pete Wentz.
The two took their son Bronx, whom they welcomed last November, to the Elizabeth Glaser Pediatric AIDS Foundation's "A Time For Heroes" celebrity carnival in L.A.
As Pete helped locals customize T-shirts, Ashlee stood by his side, making faces and smiling at Bronx, whom she held in her arms. One of her pals grabbed a white baby top so Pete and Ashlee could make a T-shirt for Bronx.
Ashlee began cracking up when a young girl approached her for an autograph and Bronx tried grabbing the girl's autograph book.
