Ashlee Simpson ran into an old girlfriend of husband Pete Wentz during E3 and turned into a drunk, unpleasant green-eyed monster.
Ashlee Simpson and Pete Wentz ran into Gossip Girl star Michelle Trachtenberg at the DJ Hero video game part at Los Angele’s Wiltern Theatre. Wentz dated Trachtenberg before Simpson.
According to PerezHilton, "The evening started off very civilly. Pete and Ashlee had a pleasant conversation with Michelle and her boyfriend for close to 20 minutes, and even showed [Trachtenberg] some baby pictures of [Ashlee's] little boy, Bronx."
Things turned sour when Simpson started drinking. An insider says things got out of control when “Simpson began to give Wentz a lap dance while staring directly at Michelle and hurling insults at her. She was grinding up on Pete like a stripper.”
Then Simpson is reported to have screamed at Trachtenberg: “I hope you know, the whole time you were dating Pete, I was f###ing him!"
Simpson later apologized.
