(CBS) If you want proof that 40 is the new 30 in Hollywood, then look no further than actress Jennifer Aniston.

She turns the big “Four-O” and she’s never been hotter, Early Show national correspondent Hattie Kauffman reports.

It happens to all of us. Our “Friends” start turning 40, including Aniston, who shared her thoughts about it with Ellen DeGeneres.

“I did have a moment over the weekend. I had my first, ‘Ahhh! I don’t want to, I don’t want to!’ I found a really long gray hair and it kind of flipped me out,” Aniston admitted.

On the hit series, “Friends” we all watched her character Rachel wrestle with turning 30.

“Conventional wisdom in Hollywood is that when you turn 40 as an actress your movie career cools down, but Jennifer Aniston seems to be going to opposite direction,” said Entertainment Weekly writer Adam B. Vary.

In fact, her last film, “Marley & Me,” has taken in $140 million and her newest, “He’s Just Not That Into You,” is currently number one.

“A lot more women are independent and not married and going into their 40′s and look at Jennifer Aniston I think that that person reflects my life, and so I think that it just bodes well for her,” Vary said.

Of course 40 is a bit more fabulous when you look like Aniston.

The birthday girl posed in her birthday suit for GQ Magazine. She told Early Show co-anchor Harry Smith that her secret for staying in shape – intense yoga workouts.

“You’ve got to see that breath of fire,” Smith said.

“I’ve got to get that fire before I calm down because if I’m going to work out, I’ve got to have it mean something,” she said.
40 forty this year, including Renee Zellweger, Jennifer Lopez, Catherine Zeta-Jones and Mariah Carey.

And it’s also worth noting that a lot of sexy men will be turning 40 this year as well, including P-Diddy, Matthew McConaughey and Javier Bardem.

“It’s my time. Every woman that’s ever said, or man, that said ‘It just gets better.’ I just agree,” Aniston told Smith.

She will next star opposite the very handsome Gerard Butler.
