Jennifer Aniston on Turning 40

Jennifer Aniston opened up about turning 40 on Ellen DeGeneres' show as the two visited on the set of Friends and shared birthday cake. "I feel better than I ever felt in my life," Aniston said, whose birthday is on Feb. 11. "I did have a moment, though, over the weekend. My first, like, 'Huh, … I don’t want to [turn 40].' I found a really long gray hair and it kind of flipped me out. It’s not my first but it’s the fact that it was so long." (Photo: WENN)
