The Master of Darkness needs to lend a crying shoulder to his newly heartbroken daughter. Kelly Osbourne broke off her engagement to British model Luke Worrall after numerous rumors of him being unfaithful.

Worrall's alleged infidelity erupted into a celebrity Internet feud over both Worrall and Osbourne's Facebook and Twitter accounts (the Facebook messages have since been deleted).

Eventually, Osbourne tried to take the high road on her Twitter account, writing, "Thank you all so much for your support but the matter is private and will not be commenting enough damage has already be done!"

But haters continue to flood Osbourne's accounts with digs, including some about how Osbourne should have expected Worrall to cheat because he's so much better looking than her.

"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 f--k yourself!"," Osbourne wrote back. Another commentator chimed in with, "i hope @MissKellyO 's split from Luke Worrall won't mean she'll pile back on the pounds..." to which she replied "@ollie_lloyd fuck you".

Osbourne soon did the sensible post breakup thing and flew off to Las Vegas to party.

This is Kelly Osbourne's life since the Osbourne family was placed into the limelight with the early MTV reality show hit, The Osbournes. The show followed the family (particularly mumbling patriarch Ozzy Osbourne) throughout its daily life in England and introduced Kelly Osbourne into the public eye.

Kelly has made some attempts at a mediocre music career, and was recently back in the spotlight as a competitor on Dancing with the Stars. I better be careful what I write though. Kelly once defended Worrall (when they were still together) by slapping a columnist for The Mirror, who mocked him in an article.

If it's a choice between getting slapped or be being forced to eat a bat head, I'll take the slap though.
