Zelda Williams attends fashion gala in LA as late father Robin's widow blames his death on 'nightmare' battle with Lewy body dementia

She was left devastated when her father, Hollywood actor Robin Williams, was found dead at his home in August last year.

And while she continues to deal with her tragic loss, Zelda Williams cut a content and relaxed figure as she attended the Self-Portrait Welcome To LA dinner, held at NeueHouse in Hollywood on Tuesday evening.

The 26-year-old looked sensational in a chic black dress as she joined American star Aurora Perrineau at the lavish affair.

The sizzling ensemble, which boasted a netted skirt and a semi-sheer bodice, highlighted her slender curves perfectly.

With her raven-coloured tresses left loose in stylish waves, Zelda beamed with happiness as she stopped and posed for pictures.

Her sighting comes soon after her stepmother, Susan Schneider, discussed the final year of Robin’s life in an emotional interview on Good Morning America.

‘We were living a nightmare,’ she confessed in her first interview since the actor’s death.

The Good Will Hunting star, who died on August 11, 2014, battled depression throughout his life and it's thought to have got worse following his diagnosis of Parkinson's Disease.

But Robin’s third wife revealed the actor was dealing with Lewy body dementia, a disease that causes a progressive decline in mental abilities.

She claimed that the actor’s health problems would have killed him within three years if he had not ended his own life. 

‘If Robin was lucky, he would've had maybe three years left,’ said Susan. ‘And they would've been hard years. And it's a good chance he would've been locked up.’

The last month of Williams' life was difficult for the actor according to Schneider, and he appeared unable to keep things together.

In his final week doctors had finally made the decision to check him in for testing, and that played a big role in his decision to take his life according to Schneider.

'I mean, there are many reasons. Believe me. I've thought about this. Of what was going on in his mind, what made him ultimately commit - you know, to do that act,' said Schneider. 'And I think he was just saying, "No." And I don't blame him one bit. I don't blame him one bit.'
