We don't know much about Kai's identity, but we know that her famous relative is a female and that the biggest award they've received is a Grammy. During the fashion show in the fourth episode, Kai's clue was a long white dress with a halter top neckline. "If you know my sister, you're going to know this dress immediately," she says. While Dominique thinks that the dress could be related to Billie Holiday, who was recently portrayed by Andra Day in the movie, "The United States vs. Billie Holiday," she is proven wrong during the elimination ceremony. Kai is not related to Day and her celebrity relative is still in question.
However, in episode five, Louise chooses to reveal a clue about Kai as a reward for being captain of the winning team during the challenge. The clue confuses Louise, but it's revealed to the viewers that the clue represents the words "Fun Knee Woman in Girls Trip." While she doesn't work out Kai's complete clue on camera, she appears to be onto the "Girls Trip" part at the end.
During the sixth episode, it's revealed that Kai's celebrity relative is her sister, Tiffany Haddish, who starred in "Girls Trip." In fact, Kai's real name is Jasmine, which she shared after Amara correctly guessed her relative. "I am an ABA therapist and game designer," she shared. "I am super duper proud of my sister. Our life was not easy and to see her success and her shine and how she is so graceful and always inspiration to me."
Answer: Kai is Tiffany Haddish's sister.
