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.

Ashlee also wrote on her Twitter to Perez: “WRONG.my husband is an amazing dj and was dedicating songs to me.We were just havin fun.Our love is amazing. Get ur own life.” And as PopEater pointed out, Ashlee and Pete exchanged several inside joke-ish Tweets that seemed very sweet and normal. And whatever, couples fight. Is that a story, in and of itself? Pete goes out partying all the time, while Ashlee stays home with their son a good deal – at least according to previous stories. She might have a little well-deserved drama pent up. I’m kind of medium with Ashlee and Pete – they’re not the best or the worst. But it’s like, Perez versus anyone, you always pick the other guy/girl. It could be Perez versus a sea sponge, and I’d be defending that asshole sponge to the bitter end.
