Ellen DeGeneres may be ready to call it quits on her daytime talk show as pressure builds with claims of the host perpetuating a toxic work environment, DailyMail.com can reveal.

An insider at Telepictures tells DailyMail.com that the host is telling executives at Telepictures and Warner Bros that she has had enough and wants to walk away from the show.

‘She feels she can’t go on and the only way to recover her personal brand from this is to shut down the show,’ they said. ‘The truth is she knew what was going on, it’s her show. The buck stops with her. She can blame every executive under the sun – but Ellen is ultimately the one to blame.’

‘Don’t think for a minute anything she has said in that apology means anything. She created and then enabled this toxic culture to go on for so long,’ one staffer, who spoke to DailyMail.com on condition of anonymity, said. ‘If anyone had come to her or those three vile EPs [executive producers] to complain, they would’ve been fired.’
