Nicole Richie: Son is wild like me

Nicole Richie says her son Sparrow is "wild" like her.

The designer described her two children's different personalities and revealed that while her daughter Harlow, four, looks like her, she is taking after her father Joel Madden in personality.

The 30-year-old added that her little boy, two, is a lookalike of Good Charlotte rocker Joel but has inherited her adventurous spirit.

"My daughter looks exactly like me, and she has Joel's personality. She's very careful. She doesn't make a move without fully thinking about what the consequences would be and what that means," Nicole told Ocean Drive magazine. "[Sparrow] looks exactly like Joel and has my personality. He's just wild. I'm in for the ride. We've had broken fingers, we've been to the hospital - you cannot take your eye off of him for a second. He is just a full, free spirit."

The TV star also spoke about how she has matured over the last decade.

Nicole shot to fame as Paris Hilton's best friend on their successful reality show The Simple Life, but the pair famously fell out in 2005 over an undisclosed incident

The adopted daughter of singer Lionel Richie has openly struggled with substance and weight issues but turned her life around following the birth of her two children.

"You have to remember that I was 20 years old. I don't know anybody who can look back at who they were at 20 and say, 'I'm the exact same person.' It's all about evolving and growing. Who we are in our 30s is obviously very different than who we are in our 20s," she said.
