kelly_osbourne_jc.jpgRumours headlining today claim that Kelly Osbourne is secretly engaged to her boyfriend, Matthew Mosshart. The couple, who have been dating for just over a year, reportedly got engaged just before Christmas.

According to sources who spilled to Us Weekly, Kelly and Matthew are "really excited" about walking down the aisle.

"Kelly is the happiest she's ever been," a friend of the E! Fashion Police co-host said. "Her career is going well, and she's in a healthy relationship with a wonderful guy."

Osbourne and Mosshart, who is a vegan chef, first met a year and a half ago at the wedding of her good friend, Kate Moss. The pair were first spotted out in public together in December 2011 when they were snapped kissing on the streets of New York.

Since then Kelly hasn't been shy in revealing her true feelings for her beau. In June she tweeted: "I'm in love and I don't care who knows about it!"

This was followed by an interview with UK magazine, Fabulous, in October in which she said: "I couldn't believe that he truly liked me because I never think people ever could. But I'm so happy. I don't think I've ever really known what love is like before."

So far reports haven't been confirmed by either party.

This isn't the first time that the daughter of Ozzy Osbourne has been engaged. In November 2008, she was engaged to male model Luke Worrall. The couple split in July 2010 after he allegedly had an affair with fellow model Elle Schneider.
