The 32-year-old 'Jumper' star actress said being into healthy habits helped her enjoy life more, reported E!Online.
"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'," Bilson said.
"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," she said.
