Rumor has it Kelly Osbourne and boyfriend Matthew Mosshart secretly got engaged just before Christmas! US Weekly reports that the couple, who have been dating for over a year, is “really excited” about taking the next step in their relationship.

“Kelly is the happiest she’s ever been,” an Osbourne pal said. “Her career is going well, and she’s in a healthy relationship with a wonderful guy.”

Osbourne’s family (parents Sharon and Ozzy and siblings Jack and Aimee) has given Mosshart their stamp of approval as well. “Matthew is a stand-up guy,” a source close to the Osbourne clan tells Us. The couple is even already starting to plan their nuptials, set to take place this summer in the UK.

Osbourne and Mosshart first met about a year and a half ago, at her friend Kate Moss’ wedding in July 2011. They first stepped out in public in December 2011, smooching on the streets of New York.

Congrats to the couple!
