Aniston 'flipped' over grey hair

Jennifer Aniston has admitted that she "flipped out" when she found a particularly long grey hair.

The actress, who turns 40 on February 11, revealed that she feels amazing for her age but panicked at the recent discovery.

"I have to say really, I feel better than I ever felt in my life," she told Ellen DeGeneres on her US talkshow.

"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 grey hair and it kind of flipped me out. It's not my first but it's the fact that it was so long.

"I was like, 'Oh, how many others are there and what does that mean?' It actually brought me to tears slightly."

It was recently reported that Aniston turned down a $10 million (£7 million) offer to pose nude for Playboy.
