Nicole Richie has admitted that her heroin abuse caught her by surprise - because she didn’t think heroin addictions happened to girls like her.

Nicole entered rehab in the spring of 2003 to get treatment for her drug problem following an arrest for possession of heroin in February that year.

She explained recently: “I just started off with marijuana, graduated to coke, then to prescription pills, and then someone was just like, ‘Do you want to try it?’”

“When I pictured heroin, I pictured some crazy crackhead with no shoes under a bridge. You never think that is going to be you. And it never was me. I was never under a bridge, and I always had shoes.”
