Rachel McAdams paid tribute to Diane Keaton. 'For over 50 years luminous on screen and indelible in life, believe me when I say there isn't an actress of my generation who is not inspired by and enthralled with her absolute singularity,' she said. 'She wore so many hats - literally and figuratively - actress, artist, author, activist, but no hat more important to her than being mother to her two children. She meant so much to so many of us.' #dianekeaton #rachelmcadams #tribute #sad #honour
