A former producer on Glee has said that "lots" of male "actors" on the show were also guilty of bullying behaviour following the revelations about main star Lea Michele.

Michele, who played Rachel Berry on the musical drama for six seasons, has issued an apology for her "immaturity" after co-star Samantha Marie Ware said that she had made her first TV job "a living hell".

Others have since come forward with similar stories, with co-star Heather Morris describing her as "unpleasant to work with" and actor Willam alleging "subhuman" treatment.

Writing on Twitter, former Glee producer Marti Noxon said: "Re: @LeaMichele. Hey, I'm all for calling out bad behaviour and even for some schadenfreude when that behaviour is punished. That said, on GLEE there were LOTS of bad actors. Who were NOT women. People in the industry know who I'm talking about. Why aren't we calling them out?

"It seems to me that women are the first to go under the bus. But a lot of males get away with being the bullies-in-chief. How come we let them get away with it? Maybe it's because as long as they earn someone money, they get a pass."

Noxon later deleted her tweets and issued a follow-up message to clarify that by the word "actors" she was also referring to male members of the crew.

"I wish to clarify an earlier statement I made and deleted because it was poorly phrased," she said. "When I said 'bad actors' in reference to my work on Glee - I was using the word actor as in 'people who took bad actions'. I wasn't referring to anybody on set specifically.

"I was on that show for one season, and only part time. By and large the people I met there were wonderful. And the crew was fantastic. But when bullies are allowed to act that way - there is a culture that permits it. That's all I was saying. Thanks. Stay safe."

Michele has yet to comment further on the allegations levelled at her.
