Kelly Osbourne secretly engaged - report

KELLY OSBOURNE has been hiding a secret from fans - she quietly became engaged a few weeks before Christmas (25Dec12), according to a new report.

Ozzy Osbourne's daughter is said to be "really excited" about heading down the aisle with vegan pastry chef Matthew Mosshart, the brother of The Kills rocker Alison Mosshart.

A source tells Us Weekly magazine, "Kelly is the happiest she's ever been. Her career is going well, and she's in a healthy relationship with a wonderful guy."

The couple first met at Kate Moss' wedding in July 2011 and has been dating for more than a year.

Osbourne was previously set to wed model Luke Worrall, but she broke off their engagement and dumped him in 2010 amid allegations of his infidelity.

Last month (Dec12), Kelly's mother Sharon predicted her daughter will one day marry Mosshart, insisting, "She's so happy she could get married tomorrow! Nothing surprises me with my daughter, she's not predictable. She's never been happier - you can always tell by her eyes. She's got really shiny eyes at the moment, so she's happy."
