Kelly Osbourne Kicks Cheating Beau to the Curb

They seemed happily in love not long ago, but Kelly Osbourne has broken up with her fiance Luke Worrall - with rumors telling that it was due to her man cheating on her.

The 25-year-old daughter of Ozzy Osbourne called off a 16-month engagement, with Perez Hilton reporting that Kelly posted a long string of Twitter messages documenting her belief that Luke was having a fling.

Meanwhile, Kelly has since deleted all of her posts, leaving just one up which reads, "Luke Worrall makes me sick!!!"

Getting support from fans, Osbourne has responded to the well-wishers, tweeting, "Thank you all so much for your support but the matter is private and (I) will not be commenting, enough damage has already be (sic) done!"
