Vegan chef Matthew Mosshart has been credited with helping girlfriend Kelly Osbourne lose the last few troublesome pounds. "Over the past two years, I've lost over four-and-a-half stone—but I've only lost the last stone since I met Matthew. That's because he cooks for me! He's a vegan chef, so he makes sure that I eat healthily," Osbourne told The Daily Mail.
