One of Robin Williams' longest-running co-stars has opened up about their relationship in a new biography, revealing how he "flashed, humped, bumped and grabbed" her during filming.
Pam Dawber was the Mindy to Williams' Mork in 1970s sitcom Mork and Mindy, the launching pad of Williams' comedic career.
In an exert obtained by the Daily Mail from the new Williams biography Robin, written by New York Times culture reporter Dave Itzkoff , Dawber has revealed how WillIams would grab her breasts, walk around the set naked and even fart on her while filming.
"I had the grossest things done to me by him and I never took offence," Dawber says. "I mean, I was flashed, humped, bumped, grabbed. I think he probably did it to a lot of people... but it was so much fun.
"Somehow he had that magic… If you put it on paper you would be appalled. But somehow he had this guileless little thing that he would do - those sparkly eyes."
Dawber said Williams, who committed suicide in 2014, got away with his behaviour because "it was the '70s after all".
She added he was "such a nice person" and had a "gigantic heart", adding that they became close and she became the big sister he never had.
"I really loved Robin and Robin really loved me. We just clicked," she said.
The actor and comedian was found dead in his home age 63, in 2014.
Robin is due out May 15.
