Osbourne 'splits from fiancé Worall'

Kelly Osbourne has apparently split from fiancé Luke Worrall.

Perez Hilton reports that the couple, who got engaged in 2008, broke up after Osbourne discovered that Worall had been cheating on her.

The pair are said to have posted messages, which have since been deleted, on their Facebook accounts.

Hilton adds that one message on Osbourne's personal page which was not removed reads: "Luke Worall makes me sick!!!"

On Twitter, she wrote: "Thank you all so much for your support but the matter is private and will not be commenting enough damage has already be done! (sic)"

Earlier this year, the 25-year-old described Worall as the "love of my life".
