Oh lord, this sounds stupid because it was probably completely avoidable. I think I’m understanding this correctly…Joe and Ashlee Simpson, Pete Wentz and their entourage were attempting to exit the Decaydance/GQ party at the Mirage’s Jet nightclub, when certain parties of their entourage were barred from doing so by a Vegas bodyguard. I guess tempers flared and Pete started yelling that his peeps be taken their waiting SUV, says the New York Daily News.

“What are you doing?” yelled Wentz, demanding that his crew be escorted to a waiting SUV. “This is my [bleeping] car! I paid for this [bleeping] car!”

From there he got shoved, Ashlee was bumped into a wall, Pete and Joe get crazy and later on, Creepy Joe told the News:

“When somebody messes with my baby, then it’s over!” Joe told us later, drawing his finger across his throat.

OK, sorry, but you’re not Bruce Willis, this isn’t a “Die Hard” movie and Ashlee probably wasn’t in danger for a moment. I have a feeling there was a lot of “Do you know who I am?” and chest-bumping going on prior to the escalation of physical violence and either way, Joe, you know you do NOT need to be out partying in Vegas in the first place. Now, go sit down and be quiet. Grown-ups are talking.
