The actress gave a nod to her "The Last Showgirl" co-star, who has been going without makeup for over a year, on her 66th birthday.

Jamie Lee Curtis is taking a page from Pamela Anderson's book, and is letting her natural beauty be the star of the show. On Instagram, the Freaky Friday actress posted a bare-faced photo of her smiling for the camera. The only trace of makeup was the tiny bit of leftover mascara that she wasn't able to remove from the day prior.

Curtis and Anderson star together in 'The Last Showgirl' arriving in select theaters Dec. 13, then nationwide Jan. 10.

When our friends start a movement, we join it without a second thought, and this is a principle Jamie Lee Curtis believes in, too. On Friday, November 22, the actress marked her 66th birthday with a bare-faced selfie to celebrate and support her The Last Showgirl co-star Pamela Anderson’s makeup-free movement.
