July 15 (THAINDIAN NEWS) Twenty-five year old Kelly Osborne and her fiance, 20 year old male model Luke Worrall have went their separate ways after reports were leaked that Luke had an affair with a female model whom he met while working on a shoot.

In a bitter Facebook battle, Kelly posted several very angry status messages about Luke, but then deleted all of them except one, “Luke Worrall makes me sick!!!” After battling it on on Facebook, Kelly then went to Twitter to express her feelings in a more calm way.

The daughter of Ozzy and Sharon Osborne posted a Tweet on Wednesday which read, “thank you all so much for your support but the matter is private and will not be commenting enough damage has already be done!” After several people responded with mean and hurtful messages, Kelly Tweeted, “Thanks. You’re a sweet heart. So what you’re saying is that I’m ugly, so it was ok for him to cheat? Go [expletive] yourself!”

Perez Hilton was said to have released the rumors that Luke had cheated on Kelly, and claims that the third party involved was the cause of the bitter break up. The young couple had began to date in 2008 and announced their engagement last year. Back in February, however, Kelly told ‘PopEater’ that she was no where near ready for marriage. “I’m not even going there yet. We’re too young to get married. We can be engaged for a while,” she said.
