UPDATE: Kelly later told Yahoo! Movies, "I'm not engaged." So ... were these sources wrong or did something happen afterward to end the engagement?

Original story:

Lady Gaga's fans may not love her, and her mom's house recently caught on fire, but so what? Kelly Osbourne is happy and in love — and she's reportedly engaged!

Sources tell Us Weekly that Kelly, 28, got engaged to her boyfriend of over a year, Matthew Mosshart, 29, just before Christmas. (If that's true, props for keeping it private for a whole month!)

The two met at Kate Moss's wedding in July 2011. Sources tell the site the two lovebirds are "really excited" to be taking the next step and "Kelly is the happiest she's ever been."

Congrats to the happy couple!
