Kelly Osbourne, 25, and her male model fiance, Luke Worrall, 20, have split after reports he cheated with a female model he met on a shoot.
Kelly took to her Facebook wall to post several angry messages about him including "Luke Worrall makes me sick!!!" The posts have since been deleted.
Wednesday Kelly tweeted, "thank you all so much for your support but the matter is private and will not be commenting enough damage has already be done!"
A couple hours later she was back on Twitter commenting, "you can take my heart but NEVER my sense of humor!"
Then Kelly tweeted a video of 'My Lovin' (You're Never Gonna Get It)' by En Vogue.
"i have decided to comment through song and i believe en vogue says it best!" she wrote.
Kelly and Luke became engaged in 2008.
