Kelly Osbourne almost wet herself during a recent TV appearance.

The 26-year-old star - who is the daughter of Ozzy and Sharon Osbourne - was so stunned to be surprised by a person disguised as Super Mario's gorilla pal Donkey Kong on Ellen Degeneres' talk show that she couldn't control her response, much to the delight of the studio audience.

She explained: "I'm always happy to appear on Ellen DeGeneres' show, she's one of my favourites - but she loves scaring her guests.

"We were chatting about stuff when somebody dressed up as Donkey Kong snuck up and scared the s**t out of me. I screamed and I think I even weed a little!

"But because they properly terrified me everyone in the audience got a Nintendo Wii. Ellen even gave one to me."

As well as on the Ellen show, Kelly also failed to keep her emotions in check when she saw the pictures of her recent shoot for Shape magazine, admitting she broke down in tears after seeing herself look trim in a bikini.

She wrote in her column for Closer magazine: "When I saw the photos for my Shape cover shoot, I burst into tears. I honestly never thought I'd be the girl wearing a bikini on The Front of a magazine - especially considering that throughout my whole life so many people called me fat and ugly.

"I was so nervous back in September when we did the shoot but it turned out to be an amazing experience and I even got teary when I saw the first shot of the day on the photographer's computer screen.

"I'm so pleased with the pictures - I just honestly cannot believe it's me."
