“OK Kathy, we’re going to show you a photo of a person, Crystal [Kung Minkoff] will guess whether or not Kathy can name the individual, Kathy will reveal,” he explained.

Hilton first failed to recognize Ryan Reynolds and Jean Smart, but things got particularly awkward when she thought she recognized Lizzo’s face, with Minkoff guessing she’d know the answer

“I feel like I do,” Hilton said, before answering, “Precious?” referencing the character played by actress Gabourey Sidibe in the Lee Daniels film.

Cohen immediately reacted with awkwardness, saying, “Nooooo, that’s not right,” explaining that the person in the photo was Lizzo.

“She is precious though! Lizzo is precious,” Minkoff said, as the everyone else on set exchanged awkward looks.

“That’s, like, what I call her,” Hilton responded. “Her nickname is Precious to me.”

Commenting on an Instagram post about the moment, Hilton explained, “My vision is awful, the screen was so far away that I couldn’t even recognize Justin Timberlake or Melissa Etheridge🥲🤦‍♀️.”

After cycling through some more faces, she finally got “Real Housewives of Orange County” alum Vicki Gunvalson right, and almost got Joy Behar, calling her “Joyce” Instead.

On Twitter, though, people were mostly shocked by Hilton confusing Lizzo and the fictional character, Precious.
