Never let it be said that just because you’re married, life can’t be like high school. According to Perez Hilton, some major prom-style drama went down between Ashlee Simpson and her husband Pete Wentz last night. Of course Ashlee and Pete claim everything is fine, and they’re more annoyed with Perez than each other. In fact Ashlee thinks he should “get a life.” Ahhh, senior year memories.

The battle is on. Ashlee Simpson has lashed out at celebrity gossip blogger Perez Hilton via Twitter. PerezHilton.com ran a story about the singer and her husband, Fall Out Boy bassist Pete Wentz, claiming that Ashlee’s drunken partying caused a loud spat between the two at an anniversary celebration for Wentz’s bar, Angels & Kings.

Perez reports that Wentz was enjoying his party when Simpson “came up completely wasted and yells at him to leave. They fought, she told him he was horrible in front of a whole group of people and made him leave his own party early. So they make a scene and leave the bar.”

Now Simpson has used her Twitter account to scold Perez for his damaging gossip.

“When all you do is make up untrue stories- look in the mirror. Do you even feel human?? Karma is a bitch.Your story is WAY off,” the ‘Pieces of Me’ singer responds.

Naturally, Perez responded right away, tweeting directly to Simpson: “There are a lot of good rehab facilities in Malibu!” He added, “I don’t wanna name names and get people fired but several of the people I spoke with work at Angels & Kings. I’m not wrong.”

He also wrote a Twitter message to Wentz: “Sorry to hear about what Ashlee put you through last night!” The rocker made no response, but romantic messages to his wife around the same time suggest that Wentz is feeling just fine about Simpson.
