Rachel Bilson has admitted she got drugs and alcohol ''out of her system'' before finding fame.

The 32-year-old actress - who shot into the limelight in 2003 after landing a role in 'The O.C' - has managed to avoid the unhealthy pressures of fame because she'd already kicked her bad habits prior to her career.

Speaking in the June issue of Health magazine, she explained: ''I grew up in Los Angeles 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'.''

The brunette beauty then began dating her co-star Adam Brody for three years, before they split up in 2006, but she believes their relationship stopped her from partying.

She added: ''Then 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.''

Rachel is now looking to settle down and start a family with her boyfriend Hayden Christensen, whom she has been dating for seven years, as she believes she and her beau would make excellent parents.

She said: ''To start a family would be good, any year in the next few years. I've always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house.''

Speaking of Hayden, she added: ''He'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.''
