This was really the year of Colin Firth! The hot British actor swept award season and won every major honor from the Oscar to the BAFTA for his role as King George VI in The King's Speech. His proud wife, Livia, was right by his side throughout the months of red-carpet walking, supporting her own eco causes by wearing environmentally responsible gowns. Colin also had the honor of hosting this year's Met Ball, which was a tribute to the late designer Alexander McQueen, with fellow Brits Anna Wintour and Stella McCartney. He'll next tackle comedy after a string of serious roles, as he's starring opposite Cameron Diaz in a remake of the 1966 Michael Caine film Gambit. Colin makes his debut this year on the PopSugar 100 and also found a place on Time's annual list of the world's 100 Most Influential People.
