Kelly Osbourne hid her girly side to please her Rock Star father.

The 'Dancing With The Stars' contestant - daughter of former Black Sabbath singer Ozzy Osbourne - claims appearing on the talent show has brought out a different side to her.

She said: "You're definitely seeing a softer side of me and it's a side I've always been afraid to show because God Forbid Ozzy Osbourne's daughter be girly rather than a punk.

"For the last 23 years of my life I have been called moody and now I can't stop myself from smiling."

Talking about Monday's show (28.09.09) - Kelly revealed she enjoyed dancing the tango with partner Louis Van Amstel, despite being nervous.

She added: "The tango is supposed to be a really serious dance but I can't stop giggling, although I feel there is a lot of pressure on me. I don't want to look dumb."

Unfortunately her performance was met with a lukewarm reception, and she later apologised, saying she "freaked out".

Kelly, 24, is pleased with the effect the show is having on her waistline, and dancing is now her preferred way to work out.

She added: "Looking at people sweating, pretending to be look sexy with make-up in Los Angeles gyms is not for me.

"But dancing is different. And it's fun because it's a progression - every day you keep getting better."
