kelly osbourne and fianceKelly Osbourne isn't known for holding her tongue. Her life -- and that of her Rock Royalty family -- had always been an open book. That is why fans were shocked to learn that Kelly has secretly been engaged for over a month.

The E! Fashion Police co-host and boyfriend Matthew Mosshart got engaged a few weeks before Christmas. "Kelly is the happiest I've ever seen her," a source told Us Weekly. "Her career is going well, and she's in a healthy relationship with a wonderful guy." Wedding plans are already in the works.

The couple plan to get hitched in the UK this summer. Given her gig as a style critic, I imagine a gorgeous gown is her top priority. No word on bridesmaids or guest list, but you can bet that Lady Gaga won't get an invite! (Their tiff just keeps getting nastier and nastier!) "They are so excited," the insider said of the lovebirds. Especially the bride-to-be, who hasn't been so lucky in love. She was heartbroken when her model ex Luke Worrall allegedly cheated on her and they began a bitter Twitter feud.

Things, however, seem much different with Matthew, a baker. The pair met over a year ago at Kate Moss' July 2011 wedding. He has even gotten the seal of approval from the entire Osbourne clan -- mum Sharon, dad Ozzie, and big bro Jack. "I couldn't believe that he truly liked me because I never think people ever could," she told U.K. magazine Fabulous last October. "But I'm so happy. I don't think I've ever really known what love is like before." Here's hoping this is one celeb couple that actually makes it down the aisle.

Are you happy for Kelly?
