This one is going to get the older generation all hot and bothered!

Jamie Lee Curtis has decided to pose shirtless for AARP: The Magazine to celebrate her 50th birthday.

"I want to be older," she tells the magazine. "I actually think there's an incredible amount of self-knowledge that comes with getting older. I feel way better now than I did when I was 20. I'm stronger, I'm smarter in every way, I'm so much less crazy than I was then."

Curtis, who is married to Christopher Guest and the mother of two children, says she reached a turning point two years ago when a tabloid published a photo of her and gave her weight as 161 pounds.

"I was like, `How dare you — I'm not 161 pounds!' I was indignant. I got home and I went on a scale and I was 161 pounds. I was in denial about it," she says.

"So I started a really healthy way of eating, just avoiding things that I had been shoving in my mouth. Over the course of a year, I dropped about 20 pounds," Curtis says.

"Now, I get up at (5 a.m.) every day, filled with energy. I play tennis three times a week, and I do yoga."

Curtis says growing older means paring down to an essential version of yourself.

"I've let my hair go gray. I wear only black and white. Every year I buy three or four black dresses that I just keep in rotation. I own one pair of blue jeans. I've given away all my jewelry, because I don't wear it," she says.

I can't wait until I get old and nothing matters any more!
