She ready to reveal who bit Beyoncé.
Rose writes that comedian asked if she knew the identity of the culprit. Rose says she mentioned Lathan in response, which caused Haddish to smile.
"I'm super good friends with her stepmom and her dad (producer-director Stan Lathan), and they were mad at me," Haddish said. "They were like, 'Why would you do this to the family? You know, black actresses, you guys have to stick together, it's so hard for you guys to get work as it is, why would you try to ruin her career?' "
Haddish said that was never her intention.
"I didn't try to ruin her career," Haddish explained. "I never said her name! I was just trying to say how Beyoncé kept me from goin' to jail that night. I coulda just shut my whole career down."
The alleged bite made headlines in March when Haddish told GQ about the December night she met Bey at a party. Learning Beyoncé had been bitten enraged the Girls Trip actress and made her want to fight the assailant.
Haddish said telling her tale made her more popular, contrary to what some would predict.
"The other day, someone was saying, like, 'Oh my God, you should keep your mouth shut 'cause now you're never gonna be invited to parties,' but I got invited to way more parties after that," she said. "It's ridiculous how many parties."
In fact, she says, other people seem to think that feeding her info will get them press.
"They want me to talk about something at their thing 'cause they think, like, 'This is gonna put me back on if Tiffany says something,'" she explained.
Haddish had quite the story to tell GQ when she first talked about the incident. “There was this actress there,” she told the magazine, “that's just, like, doing the mostest ... She bit Beyoncé in the face.”
Continuing the story, Haddish said, “So Beyoncé stormed away, went up to Jay-Z, and was like, ‘Jay! Come here! This (woman) —’ and snatched him. They went to the back of the room. I was like, ‘What just happened?’ And Beyoncé's friend walked up and was like, ‘Can you believe this (woman) just bit Beyoncé?’ ”
Haddish told GQ Beyoncé had confirmed the bite and actually stopped her from treating the actress to a beating.
"(Beyoncé) was like, ‘Tiffany, no. Don't do that,' " she recalled. " 'That (woman) is on drugs. She not even drunk. She not like that all the time. Just chill.’ ”
Lathan, who Vulture reported also attended the party, denied the accusation on Twitter the day the GQ piece published. "Y'all are funny," she tweeted. "Under no circumstances did I bite Beyonce and if I did it would've been a love bite."
USA TODAY has reached out to Lathan's reps for comment in light of Haddish's confirmation.
