Kelly Osbourne still isn’t over her ex-boyfriend’s philandering ways. The 26-year-old star slammed ex-fiance Luke Worrall in an expletive-loaded Twitter rant. On Christmas Day, Osbourne wrote, “Wow just found something out that has hurt my feelings so bad, and Christmas was going so well…” She then sent a series of tweets warning other woman about his wandering eye.

“Luke Worrall is the biggest piece of s***. He has been trying to get back with me. I only came home for Christmas to see him, meanwhile he has been f***ing hundreds of girls, as well as men, behind my back,” she wrote.

The pair split in July after nearly two years together, amid rumors of infidelity.

She continued: “He used me for my money and a free ride. He is lucky I am not spilling the whole truth about what he did.”

“I am and always will be too good for Luke Worrall. Darling your pretty face will only get you so far because you don’t have the brains to back it up,” she wrote. Osbourne later threatened to leave Twitter for good.

Worrall was left unimpressed, commenting on his own page, “Lies on Twitter. Awesome.”

When Osbourne split from Worrall in July, the couple exchanged angry messages on Facebook, with Kelly ranting, “Luke Worrall makes me sick!” Shortly after, Perez Hilton claimed a third party was involved and accused Worrall of cheating.
