Nicole Richie was a rapper

Nicole Richie was once part of a rap group.

The reality TV star and two of her friends formed a hip-hop act called Caution and were so convinced they were going to make it they asked Nicole's mother Brenda Harvey to find them a manager.

Nicole - the adopted daughter of Lionel Richie and Brenda - wrote on her Twitter page: "When I was 10 years old, I was in an all girl hip-hop/rap group. (oh we're just getting started). Our name? get ready. CAUTION! It was me and my 2 girlfriends; but they were 13 so they made me audition.

"I was soooo excited when I got in! All I can think of is the 3 of us going up to my mom with a straight face and singing her our first song. We were dead serious.

"My poor mom had to sit there with a straight face and watch us perform and we asked her to find us a manager (sic)."

Despite the group not setting the music world alight, Nicole, 27, can still recall the lyrics to one of their songs.

She added on the site: "I even remember part of our rap. I'm getting chills of embarrassment even typing this. The rap lyrics I remember were: 'Caution! Walking down the street/You better watch out, and step to the beat/Playing our music from town to town/Rockin' and Rollin' we're gonna get down!' "
