Tiffany Haddish revealed the sneaky way she would get real feedback about her auditions during The Hollywood Reporter's annual Comedy Actress Roundtable, which was released on Wednesday.

"You know what I'd do? I'd put my phone on voice memo and put it in my bag. I'd do the audition, walk out the room and leave my bag," Haddish told the group, which included Regina Hall, Maya Rudolph, Jane Fonda, Alex Borstein, Phoebe Waller-Bridge and Natasha Lyonne.

"Then I'd come back and be like, 'Oh, I forgot my purse in there,'" she said.

The Girls Trip star recalled racially biased comments casting directors said when they thought she was out of earshot. She heard things including, "'She is not as urban as I thought she'd be,' or 'She is so ghetto.' 'Her boobs aren't big enough.' 'I really think we should just go with a White girl.'"

Haddish left her phone in "a lot" of rooms as a way to grow in her career and to get material for her jokes.

"I want to hear so that I can write jokes about it. That and also so that I use it to my advantage and grow," she explained. "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."
