Petco run! Pete Wentz and Ashlee Simpson-Wentz brought along son Bronx Mowgli (and pal Woody!) for a quick trip to pick up some dog supplies on Wednesday in Studio City, Calif.

The couple was also spotted playing at the park with their baby boy last week.

Bronx, 9 ½ months, “cracks himself up all the time,” Ashlee says. “It’s cute. It’s very entertaining. He’s like, ‘I am so funny!’ And he probably gets that from me because I make jokes that are not funny, and I’m the only one laughing.”
