Others are drop dead sexy and up front about their pot-smoking past (we're picking our jaws up off the floor, Megan Fox).
Below, Megan Fox - the star of Transformers and the hottest new actress in Hollywood - talks to Maxim about her penchant for drugs and more.
How have you avoided the cliched road to rehab? I've done drugs, and that's how I know I don't like them. Cocaine is back with a vengeance - everyone in every club is doing drugs. A lot of people are on prescription drugs. Celebrities aren't trying to hide it, except where people have camera phones.
Did you go through an experimental phase? I wanted to try several things and make an informed decision, but I didn't enjoy anything other than marijuana. I don't even think of it as a drug; it should be legalized. I know about five people who aren't on drugs today, and I'm one of them.
* The Hollywood Gossip note: Lindsay Lohan? Not so much one of them.
Finally, a celebrity who isn't afraid to tell the truth! I'm blunt and maybe too honest. But being outspoken is good for women, particularly when it come to sex. Women are supposed to be on magazine covers dressed provocatively, but they're not allowed to talk about sex? That double standard angers me.
I really enjoy having sex, and that's offensive to some people. Women are the quickest to call other women sluts, which is sad. I haven't met a lot of men who've said, "You like having sex? What a dirty whore you are!" That's because they wish their wives or girlfriends would have more sex with them.
* The Hollywood Gossip note: Megan Fox for President!
A half nude Megan Fox is heating up the pages of Maxim.
What kinds of things put you in a good mood? I'm young and have a lot of hormones. I'm always in the mood. But I like sex with one person in a relationship. Sex with random-ass people at clubs isn't what I'm about.
* The Hollywood Gossip note: Amen, Megan. Just beware of random photographer snapping sex photos of you and your mate, as Nick Lachey and Vanessa Minnillo could warn you about.
You've got nine tattoos. Are you trying to break Angelina Jolie's record? Every time I get a tattoo, it's a little ****-you to anyone who tells me not to. It's weird to be part of Hollywood, which tries to control every aspect of people, from what they say to the color of their hair. And I like the way getting a tattoo feels. If I'm depressed, it's nice to get one and deal with the pain. I have one all the way down to my ribs. It hurt, but it felt goodâ€"like twisting a loose tooth.
I'm not kidding when I say that if I ever lose a role because of my tattoos, I'll quit Hollywood and go to work at Costco.
