Kelly Osbourne reveals behind-the-scenes fights

Kelly Osbourne says the 'b****ing' has started behind-the-scenes on 'Dancing with the Stars’.

The 24-year-old star, who is currently in training for the next series of the US TV talent show, has revealed this year’s contestants are getting more and more competitive as they near the start of series.

She said: 'When I first started the rehearsals, I thought the other contestants were all lovely, but it’s suddenly become much more competitive and there’s a bit of b****ing going on behind the scenes."

Kelly admits she is dreading the opening episode because she doesn’t want to be the first celebrity voted off.

She said: 'I’ve never been so terrified about anything in my life and am praying I don’t get voted out first. If that happens I’ll probably cry for a month! I’d feel so unloved."

Although Kelly is nervous, she is pleased her parents and fiance, 19-year-old model Luke Worrall, will be in the audience to support her.

She added to Britain’s Closer magazine: 'My mum Sharon, dad Ozzy and fiance Luke will be cheering me on. I’ve never ever danced in front of people before – I feel sick thinking about it!

"There’s a rumour floating around that one of the celeb dancers has been having secret lessons for two years! That is so not fair."

Kelly Osbourne embarrassed by rocker dad

Ozzy Osbourne cut off his daughter’s underwear while her friends watched.

Kelly Osbourne was left mortified as a teenager when the Black Sabbath rocker objected to the skimpy thong her mother Sharon had bought her and insisted on forcibly removing the garment.

Kelly said: 'One time, mum bought me thongs instead of big knickers. As I bent down, dad bellowed, 'Kelly, you’re wearing a thong, Kelly? Thongs are for wh***s.’

'I jumped out of my skin. He pinned me down and cut off my thong in front of my school friends. They were standing there, mouths wide open as this piece of material no bigger than a string of dental floss was yanked out of my jeans.

'I died of embarrassment and burst into tears. Mum was hunched over the sink, laughing her head off, screeching, 'Ozzy! No!’ '

The incident was not the only time Ozzy embarrassed Kelly in front of her friends – but the presenter insists she didn’t mind, even when he chased her pals round the family garden wearing just his pants.

The 24-year-old star explained in her autobiography 'Fierce’: 'Parents are parents and they embarrass you all the time. At my 13th birthday party, dad was really drunk, chasing everyone round in his underwear and a military hat.

'All my friends were screaming and running around. It was crazy fun.

'One time dad dressed as a werewolf and locked my friends in the garden shed. The kids were crying and mum had to call their parents to come and collect them.'
