Kelly Osbourne engaged to Matthew Mosshart: 'I couldn't believe he liked me'

Matthew is a vegan celebrity chef and brother of musician Alison Mosshart, who is one-half of The Kills. Alison's bandmate, Jamie Hince, married Kate Moss in June 2011, and it was at their wedding that Kelly and Matthew met. They first stepped out as a couple six months later.

A year after meeting Matthew, Kelly tweeted, "I'm in love and I don't care who knows about it!" She also tells Fabulous UK -- in the interview that reignited the feud between Kelly and Lady Gaga -- that Matthew is her first true love.

"I couldn't believe that he truly liked me because I never think people ever could," says Kelly. "But I'm so happy. I don't think I've ever really known what love is like before."

Kelly has yet to confirm the engagement report, but she seems to be working on her wedding gown figure already. Osbourne tweeted, "Im all about Hula-hooping right now! 5mins in the morning 5 mins at night ... in 5 days I lost 2 inches from my waits line! [sic]"
