Grey power!

Viva la revolution – the sexual one, that is! Co-stars Diane Keaton (79), Mary Steenburgen (61), Candice Bergen (71) and Jane Fonda (79) play friends whose lives are changed forever after reading saucy novel Fifty Shades of Grey in the Book Club. The ladies were in Las Vegas last week to promote their upcoming film.

Cheers, girls! Book Club co-stars (below, from left) Diane, Mary, Candice and Jane are a glass act. It’s a new chapter for Diane and her pals.
