Yesterday every celebrity gossip blogger and their brother was claiming that Ashlee Simpson got sloppy drunk and confronted her husband’s ex at Monday nights DJ Hero event. One source says that although Pete Wentz and his wife had a pleasant convo with his ex-girlfriend Michelle Trachtenberg and her boyfriend..the claws came out as the drinks kept flowing.

“Pete and Ashlee had a pleasant conversation with Michelle and her boyfriend for close to 20 minutes,” says a champagne-poppin’ spywitness. ”Ashlee got very very drunk and she also kept making frequent bathroom trips.”

“As the evening went on and Ashlee started to get sloppier, things got out of control,” a partygoer confesses. “A loud and obnoxious Ashlee began giving her husband a lap dance

. She was staring directly at Michelle and starting hurling insults at her..She was grinding up on Pete like a stripper. It was actually pretty disgusting!”

A completely wasted Ashlee screamed at Michelle, “I hope you know, the whole time you were dating Pete, I was f***ing him!”

But did it really happen that way?

As Ashlee’s rep spins it…

“It was just a misunderstanding,” the publicist tells us. “Ashlee has since apologized to Michelle, and they remain on good terms.”
