Isla Fisher at the premiere of Bachelorette in L.A. (8/23)

Isla Fisher tells E! that, despite how she acts (like Lindsay Lohan?), she's not high on coke all the time, and she's actually never done it. She's just naturally insane:

The funny lady wife of Sacha Baron Cohen (and mom of their two daughters) says she never knew her pals suspected she liked to party until she made Bachelorette, her new comedy in which she plays, well, a coked-out mess.

"It's hilarious for me because I've never done coke," Fisher, 36, said at last night's Hollywood premiere of the girl-powered flick. "When I got the job, I was like, 'How am I going to wing this? I don't have any experience' ... I asked a few friends what it's like being on coke and they said, 'We thought you were always on coke!'" Fisher said. "It turns out my personality, because I speak so quickly, people always thought I was doing it! I've never even seen it."

I call bullshit on this whole thing. I'm not saying that Isla is on the yayo, I'm just saying that her friends know she doesn't do blow. Look, it's common knowledge that women are heartless bullies and will force their friends to blast a few lines just to make sure that they aren't the only coke whore in the restroom. What women never do is share coke with men, which is one of the reasons why I'm so hard on women. I'm not saying that doing coke is right, but I am saying that if you're doing it, then why not let your buddy have a taste? Isn't that right, Suri Cruise in the bathroom of the Hollywood Roosevelt Hotel on June 9th? Selfish bitch.
