Best Celebrity Pictures Week of Dec. 17, 2012

It was an exciting week for celebrities, between stepping out for award shows, spending time on exotic beaches, and celebrating friends. Kate Middleton made her first posthospitalization appearance to share the stage with David Beckham at the BBC Sports Personality of the Year awards in London, while bikini-clad Kate Moss took a dip in St. Bart's. Britney Spears donned a sexy ensemble for the X Factor finale, and Jessica Simpson walked down the aisle as a bridesmaid at pal CaCee Cobb's wedding in LA.

That's not all that went down with the stars this week. Check out the rest of the fun snaps!
