Comedian Tiffany Haddish revealed that she used to secretly record Hollywood casting directors, and disclosed the racist remarks they made about her when they thought she wasn't listening.

"You know what I'd do? I put my phone on voice memo and put it in my bag, and I do the audition, walk out and leave my bag," she said during 'The Hollywood Reporter's Roundtable.' "Then I'd come back and be like, 'Oh, I forgot my purse.'"

Tiffany was surprised by how personal the feedback was: 

"They'd be like, 'She is not as urban as I thought she'd be.' Or they would be like, 'She's so ghetto, I just can't.' 'Her boobs aren't big enough.' 'I really think we should just go with a white girl,'" she said.

She was then asked why she felt the need to hear their private feedback.

"I'm sneaky! I want to hear so that I can write jokes about it," she said. "That and also so that I use it to my advantage and grow. Like all this 'Jeez, she can't read. She said every word wrong.' And I'm like, 'They're right.' So, I start reading out loud more and practicing, and it helps me in the long run. So, sure, they hurt my feelings, and sometimes I'm like, 'Damn, what a b*tch. I'm never going back there,' but I did."
