Rachel Bilson has admitted that she "did all the drugs and alcohol" before she found fame.
The gorgeous actress starred in the hit American television show The O.C for four years between 2003 and 2007, and has said: "I grew up in L.A. and did all that when I was younger. I went to the clubs and did all the drugs and alcohol.
"I got it out of my system, so by the time I was on The O.C, I was like, ‘Wow, I can just enjoy this."

During her time on the show, Rachel dated co-star Adam Brody, and speaking to Health magazine discussed how being in a serious relationship and not being concerned about partying in Hollywood helped with the transition.
"I started dating a co-star, so it was more of a domesticated thing; you're just home or with friends—and not out to party", she said.
The 32-year-old actress can now be seen in Hart of Dixie, and has been dating fellow actor Hayden Christensen for seven years.
Rachel also discussed her unhealthy habits and a recent addiction she had to quit.
"My unhealthiest is when I binge on Flamin' Hot Cheetos, because it happens. I binge. I can admit it," she said.
"I've actually gotten better this year. It got to a point where I was eating them so much that, like, you poop red every day! You're like, ‘OK, I don't know what's going through my body, but I probably should stop. There are problems.'" she added.

Rachel also spoke of her desire to become a mother, saying: "To start a family would be good, any year in the next few years," before adding: "I've always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house."
And it seems that it could be on the cards for the pair sooner rather than later, as Rachel divulged: "[Hayden's] so incredibly supportive and considerate. It's so basic—that should be there. Because these things are so much more important when you're older.
"I've been in my relationship for seven years, so we've grown up together in a way. This is my partner, my support, just there for me no matter what. And vice versa."
