Acting legend Diane Keaton was shocked by her sisters' reaction when she confessed to her secret bulimia battle - because her siblings always knew the star had issues with food and brushed her remarks aside.
The Oscar-winning Annie Hall actress stunned fans when she revealed in her memoir, Then Again, last year (11) that she spent years gorging on food and bringing it back up in secret.
But her revelations had less impact on her loved ones, who suspected Keaton suffered an eating disorder at the time.
She tells Aarp magazine, "With bulimia, I never expected sympathy or for people to understand. What I cared about was the secret I kept. It felt like a burden. I never told my mother.
"But when I finally told my sisters many years after the fact, they weren't that shocked. My sister Robin said, 'Yeah, you ate a lot of hamburgers back then.' It's amazing how the dark secrets inside us don't matter much to the outside world."
