Kimberly Wyatt gets mistaken for Sarah Harding

The Pussycat Dolls singer is a huge fan of Girls Aloud and was flattered when people confused her with the 28-year-old beauty after she experimented with a new hair colour and style.

She said: "I was mistaken for Sarah Harding quite often when I was blonde.

"I love Girls Aloud. I'll never forget watching one of their videos when I was over here in England with the Dolls – it's like a video full of models."

As well as praising Girls Aloud, Kimberly, 28, is in awe of Black Eyed Peas star Fergie and wishes she had a body like hers.

She added: "Fergie's got a banging body – she's got a booty, she's got boobs and she has a tight little stomach.

"When we performed with her, she had a corset on and little shorts and I was pretty amazed by her body."

However, the star isn't a fan of everyone she has worked with, admitting rapper Ludacris infuriated all of the Pussycat Dolls with his dismissive attitude.

She explained: "I'd hate to call anybody out but Ludacris is the rudest celebrity I've met. We were working with him and he didn't give us the time of day. It was like we were his backing dancers."
