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.

Jamie Lee Curtis shared a makeup-free selfie to Instagram as a way of honoring Pamela Anderson, who consistently appears at events without makeup.
