Ashlee Simpson and Bronx Wentz Shopping at Costco in LA

Ashlee Simpson had her son Bronx along for a trip to Costco yesterday in LA, and they shared a few laughs as they headed out of the store. Ashlee seemingly has another guy in her life besides her toddler these days. Ashlee Simpson and Vincent Piazza, an actor on Boardwalk Empire, were spotted kissing and strolling arm in arm in NYC earlier this month. Ashlee and Pete Wentz announced that they were divorcing in February, and while the two have been seen out and about with their son since then, it looks like she is moving on with the new romance. Since Ashlee headed back to LA from her PDA-filled stay in the Big Apple, she has been lying relatively low, but joined famous friends like Nicole Richie and Paris Hilton last week for the launch of designer Charlotte Ronson's latest I Heart Ronson collection for JC Penney at the Roosevelt Hotel.
