"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.

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.'"
