Looks like motherhood hasn’t matured Ashlee Simpson much. Perez Hilton says that the singer recently went off on Michelle Trachtenberg—husband Pete Wentz’s ex—worse than she did that McDonalds cashier a few years back. Seems the former lovers (and their current significant others) were coincidentally seated near each other at party in LA Monday. Things started friendly enough, with Simpson showing off baby pictures. And then…

As the evening went on and Ashlee started to get sloppier, things got out of control. 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!

Simpson allegedly screamed “I hope you know, the whole time you were dating Pete, I was fucking him!” To which Trachtenberg classily responded, “I’ve never said bad things about you. I’m happy for you guys.” Simpson continued to get in the Gossip Girl star’s face until Skye Everly, wife of Blink-182‘s Mark Hoppus, escorted her out. Pete supposedly stood “mortified” throughout his wife’s rampage. Man up, dude!

Says Simpson’s rep, “It was just a misunderstanding. Ashlee has since apologized to Michelle and they remain on good terms.” We’re so sure.
