Katt Williams blasted Tiffany Haddish, and Kevin Hart came to her defense.

“[Haddish has] been doing comedy since she was 16," said Katt during a recent radio interview. "You can’t tell me your favorite Tiffany Haddish joke. Why? Because she ain’t done a tour yet. She ain’t done a special. She has not proven the ability to tell jokes back to back for an hour ...  Did you think she wrote Girls Trip, goofball? Or do you think that was already a script and they handed it to her? It’s up to you whatever you want to believe.”

Katt then added that one of the reasons she's popular is because she told the world she wants to bang white person Brad Pitt.

“They like her because she said she wants to sleep with a white man. That’s why the only thing she said was ‘I wanna give it to Brad Pitt.'”

After hearing what Williams said, Hart defended his Night School co-star on Instagram.

"[I'm] going to make you guys realize why she deserves to be up," he said. "No. 1 movie in Girl's Trip. She stars in the movie Night School with me. She's on a TV show with Tracy Morgan called The Last O.G., she's got a movie coming out that Tyler Perry did with her, Whoopi Goldberg, Tika Sumpter and many more. She's got another movie coming out with Melissa McCarthy.  The girl is working her ass off and in return received the Emmy on SNL ... What I see is a woman who's well deserving of the position that she's in ... Ultimately, one woman's success has nothing to do with yours."

Haddish — who not too long ago said she was stood up by Drake — also responded to Katt.

It’s official I made it!@KattPackAllDay talked about me and didn’t have his facts right! #Iwin #sheready I look forward to seeing you on Monday Katt, when we pick up our Emmys. I just want to shower you with REAL Love cause you need it, and I Love you 😘 https://t.co/WVOgZvwLZn
