Rachel Bilson tells the new issue of Health that she didn't become druglike Lindsay Lohan because she's got all the partying out of her system.
"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." Then I started dating a co-star [Adam Brody], so it was more of a domesticated thing; you're just home or with friends--and not out to party."
