Kelly Osbourne has confirmed she is engaged to chef Matthew Mosshart, her boyfriend of more than a year.

The "E! Fashion Police" co-host, 28, and Mosshart, 29, met at model Kate Moss' wedding in July 2011.

Osbourne and Mosshart got engaged a few weeks before Christmas, said Wednesday.

"Kelly is the happiest she's ever been," one of her friends told the magazine.

"Her career is going well, and she's in a healthy relationship with a wonderful guy."
