It's almost time to say goodbye to another exciting year in the celebrity world. Two thousand ten got off to a picture-perfect start with glamorous award season, which gave us Jennifer Aniston's famous slitted Valentino and Kristen Stewart's endearing barefoot Oscars exit. Sandra Bullock emerged from her heartbreak ready to make us laugh again at the MTV Movie Awards and Ryan Gosling and Michelle Williams made us swoon at Cannes. The Summer meant sentencing for Lindsay, new love for Jessica Simpson, and hot bikini moments from Halle Berry, Sienna Miller, and so many more. Two younger stars made splashes with their haircuts while Penelope revealed her bump, and Robert and Kristen stripped down in Brazil for Breaking Dawn. In November, the world watched as Prince William announced his royal engagement to a royal blue wearing Kate and Jake Gyllenhaal stepped out with his country sweetheart. There's so much more that made 2010 amazing, so check out our most memorable pictures of the year!
