Singer and personality Kelly Osbourne recently found herself the subject of an unsavoury prank thanks to her friend Miley Cyrus, who was hosting an episode of the newly revamped hidden camera show Punk'd. 

Former Disney star Cyrus was pranking Khloe Kardashian when she sent an actor posing as a pizza delivery guy to Osbourne's home during a girls' night in and got him to fake a rather unpleasant accident while inside the property.

The shock of the event left Osbourne reeling and hell-bent on revenge. She explained:

"This pizza delivery guy came and he asked to use the bathroom and zipped his testicles in his flies and freaks out and we all have to call 911 and figure out what to do."

"He had the most amazing prosthetic testicle I had ever seen in my life... It looked so real. I really want to PUNK her back. I was so like, 'I cannot believe you got me!'"
