Remember last summer when Kelly Osbourne tweeted that she was in love and didn't care who knew about it? Well maybe now she should tweet that she's engaged and doesn't care who knows about it! Sources tell Us Weekly that Kelly and Matthew Mosshart secretly became engaged a few weeks before Christmas last year. An insider also tells the mag that this is the happiest Kelly has ever been and that the two can't wait to take the next step in their relationship. Congratulations from CelebTV!
