Drew Barrymore and Cameron Diaz -- who co-starred in two "Charlie's Angels" movies -- enjoyed a girls' day out and Barrymore posted a picture on Instagram to commemorate it.

"#beautyjunkieweek #sisters. getting out of your house with your girlfriend. And being a whole person, with your sister. Remember to spend a moment with the ones you love in your busy life. She has made me feel beyond beautiful," Barrymore wrote Friday in her post.

"Always has. Always will. #thankgodforyourfriends. They rejuvenate and confirm everything."

The message shows the blonde actresses wearing little or no makeup, casually dressed and with their heads together.
