The E! Fashion Police cohost, 28, and Mosshart, 29, quietly got engaged just a few weeks before Christmas, sources close to the couple confirm exclusively in the new issue of Us Weekly. Dating for over a year, the pair is “really excited‘ about taking the next step in their relationship, one source tells Us.Celebitchy reveals that 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 thestreets of New York.It must be difficult to find a good boyfriend who won’t use you if you’re famous and especially if you have a very famous family in tow as well. Hopefully, they’ll be very happy, Kelly won’t wear a pink wedding dress, which would clash terribly with her lavender hair. Congrats to Kelly and Matthew!
