Kelly Osbourne has certainly grown up since her days on “The Osbournes”, which were mostly spent fighting with her brother Jack, yelling at the family’s troupe of dogs, and recording Madonna covers. These days, she’s a co-host on E!’s “Fashion Police”, is loving auntie to Jack’s baby girl, and is ready to marry the love of her life.

Osbourne and beau Matthew Mosshart got engaged right after Christmas, it’s being reported, and are planning to marry this summer in the U.K. The pair have been a couple for a little over a year after meeting at a wedding.

“I couldn’t believe that he truly liked me because I never think people ever could,” she said in an interview last October. “But I’m so happy. I don’t think I’ve ever really known what love is like before.”

Of course, Kelly still makes headlines for being her cheeky self; earlier this month it was reported that she’s been in an escalating feud with Lady Gaga (perpetuated by Gaga’s fans), which prompted her mom Sharon to speak up on her behalf.
