Kelly Osbourne and British model Luke Worrall have called off their engagement.  Reportedly he had cheated on her.

Kelly Twittered:

“thank you all so much for your support but the matter is private and will not be commenting enough damage has already be done! “

Then, over an hour later Kelly Twittered this:

“you can take my heart but NEVER my sense of humor! “

“i have decided to comment through song and i believe en vogue says it best!” (with a link to the song “My Lovin’ (You’re Never Gonna Get It)”)

Osbourne, 25, and Worrall, 20, got engaged in November 2008. Worrall was often seen during the ninth season of Dancing with the Stars, sitting in the ballroom with her parents, Ozzy Osbourne and Sharon Osbourne.

Stay strong Kelly!

Kelly Osbourne is back in rehab.

Her mother, Sharon Osbourne, confirmed the news to radaronline.com late Thursday.

“Yeah, Kelly’s in rehab,” she said of her daughter.  “What else can we say?” Sharon went on tearfully. “She knew that it was the right thing to do at this point, and we’re proud that she did it. The family is all standing behind her. Kelly knew that she needed help, and she’s getting it.”

Sharon declined to say what Kelly is being treated for. 

“Kelly will tell you herself when she gets out,” said Sharon. “We just pray that everything’s going to be okay.
