LONDON: Kelly Osbourne is "terrified" about her upcoming stint on hit U.S. talent show Dancing With The Stars - because she can't dance.

The singer has signed up for the new season of the hit TV show, which begins in the U.S. on 21 September (09) - and she accepts she won't be among the pre-season favourites.

She says, "Dancing to me is like something that I've always really wanted to be able to do but I've never had the confidence... the technique... and I'm not very graceful.

"I wanted to do something different; I wanted to do something that scared me and I don't think that anything could scare me more."

And she admits that her new dancing partner, who will be revealed on Friday (21Aug09), will have his work cut out - if they're going to be a winning couple.

She explains, "A couple of years ago, I was in Chicago in the West End. I was originally meant to be Roxie (Hart) but when it came down to doing the dancing, I couldn't learn the dancing in time because I can't dance, so I went and did (jail matron) Mama Morton instead."

Osbourne will battle for dancing glory against the likes of Mya, MACy Gray, Melissa Joan Hart and Donny Osmond.

In a post on her Twitter.com blog, Ozzy Osbourne's daughter admits she hasn't got a hope of winning, unless fans vote in their droves.

She writes, "Don't forget to vote for me when the time comes. I will need all the help I can get! I can't dance to save my life."
