Sounds like things aren’t really over between Kelly Osbourne and her ex-fiance, Luke Worrall. Kelly took the time Monday to bash her ex-man on Twitter.

Many of the tweets have been deleted, including Kelly calling Luke:

“the biggest piece of s––”

And saying he was a cheater:

“trying to get back w/ me” while sleeping with “100′s of girls.”

But some tweets remain. Kelly tweeted a slew of painful messages from Christmas Day until Monday that demonstrate her hurt — even if she doesn’t say what happened.

“wow just found something out that has hurt my feelings so bad and christmas was going so well…”

“What do you do when someone lies in the darkest way and you try to tell the person that was lied 2 but they don’t believe you?”

“I think the best part of this situation is that I have been painted out 2 be the crazy 1 when all I did was tell the honest to gods truth”

Followed by:

“Thank god for my family that’s all I have to say.”

Though, that wasn’t all the Osbourne daughter had to say.

She added her embarrassment for making Twitter her diary:

“Dont think I have ever felt so stupid he made a fool of me going to be off Twitter for a while never felt heart brake like this in my life”

Poor Kelly! Though, I don’t know if Twitter is the best place for celebrities to slam eachother…but it sure makes my job fun!

Bet you’re regretting getting involved with her, huh Luke? Kinda like dating Taylor Swift.
