Daryl Hannah has revealed that she was diagnosed with Autism as a child and struggled 'debilitating shyness' as a result of the disorder.
Now 52, Hannah - who reached the very peak of her profession through roles in smash hits like Splash, Blade Runner, Wall Street and Steel Magnolias - is able to quietly manage her symptoms.
But as she rose through the Hollywood hierarchy it was a different story altogether.
'I’ve never been comfortable being the center of attention,' the stunning blonde - who dated John Kennedy Jnr. - star told People.
'It’s always freaked me out.'
The Chicago reared beauty said at times her shyness would become so overwhelming that she would rock back and forward constantly.
'I’m a grown up now,' she told the magazine. 'I’ve learned a couple of things that really would’ve made my life easier if I’d known them 20 years ago.'
Hannah, who became famous as a teenager, said that she concealed her autism from movie producers and refused to do promotional interviews or talk show appearances, 'not because I was above it, but because I was terrified.'
She added: 'I wasted so much time scared, self-conscious and insecure.'
Now the limelight has moved elsewhere, the comfortable star says her roles have changed but she's happy.
With a boyfriend of three years, a rescue pig called Molly and and a farm near L.A, her life has changed dramatically.
'Life is too short to stress the small things anymore.'
