Kelly Osbourne is single again, and hopping mad about it. She and her former fiancee Luke Worrall went through a war of words facebook, the nastiest of which came from Kelly "Luke Worrall makes me sick!!!" one status read. Finally both acknowledged that they were no longer together, and Kelly tweeted "i am not dealing with this very well :( keeping your head up is not fun! going to bed thank god for tomorrow!" Rumors are swirling, thank to Perez Hilton, that Luke was caught cheating.
