Things are gettin' pretty wild on The O.C these days -- Olivia Wilde that is. Tongues have totally been waggin' over this hot blonde's budding relationship with poor-little-rich-girl, Marissa Cooper (Mischa Barton). So, is this 20-year-old actress as much of a rebel as the character she plays on TV? Well, let's put it this way: The butterfly tattoo might be Alex's, but Olivia still has a few tricks of her own!

A Bad Girl's Guide to The O.C.
She's the hot girl you just can't figure out. The girl all the guys want, and all the girls want to be. As Alex Kelly, the sexy, high school dropout and resident bar manager on The. O.C., Olivia admits there are perks to being a bad girl (aside from making out with Adam Brody, of course). "I think the biggest perk is I get the most interesting storyline," Olivia explains. "A lot of [fans] seem really supportive of it. I've gotten a lot of really nice letters. People really seem to dig it." On a less-than-serious note, Olivia admits that her usual jeans and tee shirt combo gets a glamorous makeover when the show's hair and make-up people get a hold of her. "Alex jumps out of the shower and she's got like three hours worth of make-up on," she jokes. "People think the blue streak [in my hair on the show] is real, and they come up to me all the time and ask me where it is. Alex is so different from me. I'm very low maintenance."

I Heart Mischa
Talk about tongue-tied! Both Olivia and her costar, Mischa Barton can't say enough about working together. Especially Mischa, who recently admitted that she would rather swap spit with Olivia than any of the guys on the show! When confronted with the info, Olivia can't help but laugh. "It was a hilarious quote," she exclaims, chuckling. "I love it! I want to go on record and say thanks Misch!" The reality (besides the fact that Olivia is married in real life, and Mischa has a BF), Olivia explains, is that girls just seem to get each other in a way that guys don't. "We have conferences before each scene to make it very realistic," she reveals. "We analyze everything from a kiss to what our characters are thinking. I don't know if guys do that, but it really helps us feel so comfortable with each other." Olivia is also quick to point out that making out with Adam Brody is as equally chill - just different. Why? Olivia says it's because she really digs his better half, GF and costar Rachel Bilson (Summer). "Rachel is probably the coolest person I've ever met," she confesses. "[She and Adam] have such a great relationship, and when you see them kiss each other, it's sooo sweet. When they kiss on the show you know it's coming from a real place."

By The Book
While Olivia has quickly made a name for herself in the biz thanks to a supporting role in last year's Girl Next Store, and her brief starring stint on the now-defunct TV series, Skin, she admits she's itchin' to get her feet wet in the family business. For most of us that means being a doctor or a lawyer, but for Olivia it actually means following in the famous footsteps of her father and grandfather who are both well-known writers. "I've recently become really interested in screenwriting," she says. "As an actor you're a storyteller, and I feel like there's a huge connection between writing and acting." If that's the case, we had to wonder what kind of ending she'd write for her character. Unfortunately for us, she refuses to give up the goods on that particular plot point, other than to hint that her character won't be making Orange County her permanent home away from home forever. "I'll miss playing Alex, but I'll definitely take her with me when it's over."

You can catch Olivia and the rest of the cast of The O.C. Thursday nights on Fox at 8:00 PM (ET).
