Kathy Griffin has some harsh words for Andy Cohen after the Bravo host claimed he didn’t know her.

Speaking to TMZ, 49-year-old Cohen was asked if he had spoken to Griffin since becoming her replacement as Anderson Cooper’s co-host on his CNN New Year’s Eve special.

“Who? I don’t know her,” Cohen said, referencing a Mariah Carey line. “I’m trying to remember [her].”

Griffin heard about Cohen’s comment and did not take it lightly, going on Twitter to blast her former boss.

The two worked together on the comedian’s Bravo series “Kathy Griffin: My Life on the D-List” between 2005 and 2010, when Cohen served as an executive for the Bravo network.

Apparently that was just the warm-up. On Saturday, Griffin posted a 17-minute video to YouTube and her social media accounts in which she continues to go after Cohen, and also blasts TMZ founder Harvey Levin — even revealing his private cellphone number.

“I just want you guys to know Harvey Levin, Harvey Levin a blogger, is very much in bed with everyone from Hollywood to Donald Trump,” she says in the video. “Doesn’t that bother you, that the president of the United States is talking to a gossip blogger?”

She goes on to accuse Levin and TMZ of fuelling the controversy that erupted after she posed with the fake decapitated head of Trump, which led her to be investigated by the Secret Service.

“I was on the no-fly list for two months, so every single airport I have gone to, I have been detained alone,” she complains.

“They have done hit pieces on me to the point where it’s actually affected my career,” Griffin adds. “Harvey Levin, have you ever done anything honourable, ever?”

Blasting Levin as “the gay male version of Kellyanne Conway,” she adds: “I just want everyone to know TMZ is very much in bed with this administration. I ran out of f**ks to give, Harvey.”

Then, Griffin continued her attacks on Cohen. “People like Harvey Levin and Andy Cohen, honestly just live to take women down,” continues Griffin, who alleges that the “Watch What Happens Live” host offered her cocaine on several occasions.

“He is going to say he was kidding: no,” accuses Griffin. “He was asking me to do cocaine with him. That made me very uncomfortable.”

In addition, Griffin adds: “The whole time I was working [at Bravo], I didn’t know how Andy Cohen wanted to be me. I didn’t know when they ended ‘The D List’ and I desperately wanted to do a talk show, Andy Cohen would be the first television executive in the history of television to give himself a talk show. Which seems to get picked up every season.”

Cohen responded to Griffin’s accusations by calling her story “100 per cent false and totally made up.”

Earlier this year, Griffin was fired from the annual CNN special after posing for a photo in which she was holding a bloody fake severed head that looked like President Donald Trump.
