Kathy Griffin is calling out Andy Cohen for saying he doesn't know her.

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.

"Even when it's on tape, there are doubters? He is NOT kidding w paps. Was my boss for 10 years. Treated me like a dog. Deeply misogynistic," she wrote.

Cohen was an executive at Bravo during Griffin's Bravo reality show "Kathy Griffin: My Life on the D-List," and produced several of her Bravo specials, including "Kathy Griffin: 50 & Not Pregnant."

He claimed to not know the actress in an interview with TMZ published Friday.

"Who? Who?" the producer said when asked if he spoke to Griffin before replacing her as Anderson Cooper's co-host on CNN's New Year's Eve special. "I don't know her."

Cohen confirmed Oct. 11 that he will host the NYE special with Cooper, his longtime friend.

Griffin co-hosted the show with Cooper from 2007 to 2016, but was fired from CNN in May after taking part in a controversial photo shoot aimed at President Donald Trump.

Griffin told The Cut in August that her friendship with Cooper is over.

She referred to Cooper, the son of artist and socialite Gloria Vanderbilt, as a "spineless heiress" in an interview with The Daily Beast published Oct. 22.
