The 56-year-old actress and television personality slammed Cohen, her former boss, in a tweet Friday after the Bravo star pretended to not know who she is.
Kathy Griffin arrives at San Francisco Gay Men's Chorus' 11th Annual Crescendo Gala Fundraiser in San Francisco, California on March 12, 2017. Before beginning her attack on Levin, Griffin tells her followers that she "didn't have a minute" to call him, but encouraged them to do so.
Cohen doesn't point out any specifics of Griffin's tirade which included details that he and executives at Bravo did not support her while she was filming My Life on the D-list and how he offered her cocaine on multiple occasions.
Cohen replaced Griffin as the co-host for CNN's New Year's Eve Celebration alongside Anderson Cooper after she was sacked, so it's no surprise there's bad blood.
Shortly after the incident, Cooper claimed on Watch What Happens Live that he and Griffin were "still friends" saying, "Look, I said what I said about - I didn't think what she said was appropriate, but I wish her the best and I hope she bounces back". So once again we're alone in an office and he's like, 'Wanna do some coke?' And I'm thinking, 'He's serious!' Trust me, he's going to say he's kidding and everything, no.
"I don't know", Mr. Cohen insisted, smiling. "He was asking me to do cocaine with him, that made me very uncomfortable".
Cohen, who has been on a speaking tour with longtime friend Cooper for years, later replaced Griffin as co-host of CNN's New Year's Eve celebration after the network axed Griffin in the photo fallout.
Kathy Griffin is calling for a new head on a plate. Was my boss for 10 years.
Griffin ultimately circled back that her goal was just to make people laugh - but proposed that Levin was attempting to blackmail her and coordinated her drama with Cohen. "Treated me like a dog". Twitter also lit up with reactions to Griffin's video.
