Cover Girl: Rachel Bilson on In Style's Your Look

How cute is she? Now if you really want to be put over the edge, you won't want to know that the jeans she's wearing in cover picture is a favorite pair she's had since she was 13. Ouch!

The former OC star dished on her style vibe and more:

"I like to add my own thing to an outfit. Like, if I'm wearing a fancy dress, I'll put a beanie on. I'm a huge vintage fan. My favorite pieces? A pair of bell-bottom-y Levi's I've had since I was 13. I've had them patched five times, and the zipper is busted, so it's always down. Ridiculous, but I won't give them up!

For my 25th birthday I had a coed sleepover. We had candy and all these party favors - My Little Ponies, Barbies. We played the board game Battle of the Sexes - girls against the boys. The next morning, the girls cooked a huge breakfast. It was amazing.

I don't talk about my breakup with Adam [Brody]. I don't want the world to know everything. It feels awkward. Invasive.

For my last meal, I'd eat: Chocolate chip cookie dough."
