Kelly Osbourne and British Model Luke Worrall called off their engagement of a year and a half amid reports that he had cheated. "Enough damage has already [been] done," Osbourne Tweeted, adding that she wouldn't be commenting further. That's okay: Mom Sharon had more than enough to say. "She's very, very sad right now, but she'll get over it. We all do," the Osbourne matriarch said." "I don't know any of my girlfriends who have never had their heart broken and end up with the first guy. I don't know anyone that has happened to."
