Kate McKinnon has revealed she was diagnosed with geographic tongue.

During a recent interview with People magazine, the Saturday Night Live alum opened up about the “inflammatory but harmless condition affecting the surface of the tongue,” according to the Mayo Clinic.

“I took a photo of my tongue and sent it to an actor friend of mine,” she said when asked about the most recent photo she took on her phone. “We both have the same medical condition. It’s called geographic tongue. Your tongue sheds in patches and looks like an atlas, hence the name ‘geographic tongue.’”

With geographic tongue, patches on the surface of the tongue are missing papillae, which are tiny, pinkish-white bumps, the Mayo Clinic states. The patches will typically appear in one area and then move to a different part of the tongue. While the condition doesn’t cause health issues, it can sometimes cause tongue pain or make it more sensitive to certain foods, including spices, salt and sweets.

“It’s gross,” McKinnon added. “We brag about how geographic we are on any given day. Maybe I shouldn’t be saying this in a magazine.”

After starring on SNL for 10 years, she left the long-running sketch comedy show in 2022 after the conclusion of season 47. She later returned to host in 2023 during season 49.

McKinnon has also starred in the blockbuster Barbie and, more recently, The Roses, alongside Olivia Colman, Benedict Cumberbatch and Andy Samberg. The latter film follows Ivy and Theo, a dysfunctional married couple played by Colman and Cumberbatch, whose picture-perfect life together gets upended when Ivy’s career takes off, but Theo gets fired from his job. McKinnon and Samberg play friends of the troubled couple.
