The Hollywood heartthrob reached the landmark in May and, rather than worry about getting older, George is embracing a new decade of his life.
During an appearance on `The Late Show with David Letterman`, he said: "I just hit 50 ... it`s cool ... I`m fine with it, it`s good fun! I guess it`s better than [being dead]."
The actor - who is dating former WWE wrestler Stacey Kiebler, 31 - attended the premiere of his new movie `The Ides of March` in New York on 05.10.11 and revealed he is grooming his co-star Ryan Gosling to take People magazine`s Sexiest Man Alive title.
George is a two-time winner of the honour and he thinks Ryan has what it takes to snatch the annual title away from last year`s recipient Ryan Reynolds.
Speaking on the red carpet at the premiere at the Ziegfeld Theater, he said: "Listen, Brad (Pitt) and Matt (Damon) and I are going to sit him down and go through some of the things he should do for the campaign."
Like George, Brad has been named People`s Sexiest Man Alive twice in 1995 and 2000, while Matt was bestowed the accolade in 2007
