The Orange Is the New Black star snapped a selfie with Jenner which she posted to Instagram on Sunday night, writing, "@caitlynjenner and I finally met in person at a special private advance screening of #IAmCait. #TransIsBeautiful #girlslikeus."
Cox, a transgender actress and outspoken advocate for LGBTQ rights and causes, has frequently spoken about the spotlight Jenner has helped shine on trans issues and the trans community, and was one of the people Jenner thanked after introducing herself to the world in Vanity Fair.
Cox has also been a trailblazer in the community, becoming the first transgender performer to ever got nominated for an Emmy and the first transgender person to ever appear on the cover of Time magazine.
