Nicole Richie doesn’t dwell on the past

The 28-year-old socialite-turned-designer - who has previously been arrested for possession of heroin and spent time in rehab – refuses to revisit her troubled history because she is so happy now.

Nicole - who has two children, Harlow, two, and four-month old Sparrow, with boyfriend Joel Madden - said: "You know, I'm one to live in the present and enjoy the time that I'm having.

"Going back into my past is just not something that I do. Right now, I'm living my dreams. To me, I've accepted responsibility for what I've done and I don't really try and look at why I did it.

"I just feel that I have gotten past it and moved on, and it's just something that's not really a part of my life any more."

Nicole also revealed she doesn't think of her friends, who include Lindsay Lohan and Paris Hilton, as famous.

The sexy star – whose adoptive father is singer Lionel Richie - told Marie Claire magazine: "I don't look at those people as celebrities. I look at them as people. I live my life and I do what I do, and sometimes you forget that people are watching you."
