Jamie Lee Curtis Nude - WTF!?

To celebrate her 50th birthday, Jamie Lee Curtis has ditched her bathing suit in favor of her birthday suit — at least partially. She looks good, too.

It’s true, people. The cover of the new issue of AARP The Magazine shows Jamie Lee Curtis topless, standing up to her chest in a swimming pool.

“If I can challenge the old ideas about aging, I will feel more and more invigorated,” Curtis said in an interview for the May/June issue.

This isn’t the first time that Jamie Lee Curtis has “dared to bare” to challenge Hollywood’s traditional definition of beauty.

In 2002, she posed for More magazine in only her underwear and bra, sans any sort of makeup, stylists and flattering camera angles or lenses.

The resulting photos showed a nearly-nude Jamie Lee Curtis as middle-aged mom, not glamour queen — complete with sagging belly and chunky thighs.

Basically, they resembled Britney Spears photos, circa 2006-present. Not that we are complaining - we prefer a few more pounds to waifs like Kate Bosworth.

This from a woman known for a bodacious body and starring roles in movies like Trading Places, A Fish Called Wanda and Halloween.

“Much of the shoot was Jamie Lee Curtis’ idea — she became very involved in the creative concept,” AARP The Magazine deputy editor Nancy Graham said. “It is certainly groundbreaking for us, and for women of this age.”

“We’re thrilled to have such a known Hollywood icon embrace her age and show everyone it’s OK to be comfortable in your own skin.”
