Hairy Moment: Kelly O Reveals Unfortunate Beauty Secret

Kelly Osbourne has been looking undeniably glam of late but she still has her beauty hang-ups to deal with, just like the rest of us.

Appearing on US chat show, Lopez Tonight, the super-svelte star confessed that she has a moustache thanks to mum Sharon.

Ms O, who looked stunning in a skin-tight black dress and sky-high platform heels, revealed that Sharon accidentally burned her upper lip with a home waxing kit when she was just thirteen.

"I was the crash test dummy," she said. "The wax was so hot that it burned me. By the time she pulled the wax off, my skin went with it and I had to go to school with a scab moustache."

Kelly, who was giggling as she told the story, admitted that she is now stuck with a moustache, which she has to wax.

The star went on to talk about her recent weight loss and newfound confidence, which she attributed to Louis van Amstel, her partner on Dancing With the Stars.
