Sarah Silverman has apologised for comments she made this week about Louis C.K. and one of his sexual harassment victims, comedian Rebecca Corry.

In an interview with radio host Howard Stern, Silverman revealed Louis C.K. had performed a sexual act in front of her, something he admitted to doing to several women in the comedy world, but claimed her situation was different to theirs.

“It’s not analogous to the other women in this that are talking about what he did to them,” Silverman said in the interview.

“He could offer me nothing. We were only just friends. So sometimes, yeah, I wanted to see it, it was amazing. Sometimes I would say, ‘F***king no, gross,’ and we got pizza.”

But Corry, who along with four other women went to the New York Times with accusations against C.K., disagreed with Silverman.

“To be real clear, CK had ‘nothing to offer me’ as I too was his equal on the set the day he decided to sexually harass me,” Corry, 47, tweeted.

“He took away a day I worked years for and still has no remorse. He’s a predator who victimized women for decades and lied about it.”

Silverman, 47, conceded she was wrong.

“Rebecca I’m sorry. Ugh this is why I don’t like weighing in. I can’t seem to do press 4 my show w/out being asked about it. But you’re right- you were equals and he f***ked with you and it’s not ok. I’m sorry, friend. You are so talented and so kind.”

C.K. has controversially returned to the comedy stage in recent months, doing surprise gigs at comedy clubs in New York City.
