Ashlee Simpson Shimmies in South Beach

Bacardi B-live threw a bash at Cameo last night, with Travis Barker and Pete Wentz hitting the turntables. Wentz arrived with girlfriend Ashlee Simpson. The twosome held hands the entire time says a spy. "They were inseparable,” says the spy. However, when Wentz invited Simpson into the DJ booth she quickly declined. Says our source, “She was dancing on a banquette and told Pete she didn’t want to give up her position.”
