Janelle Monáe's pescatarian diet led to some unexpected health problems for the singer.

In a new interview with The Cut, the singer revealed that she was diagnosed with mercury poisoning after she cut out meat for seafood, but that she’s now on the mend. While she didn’t go too in-depth about her diagnosis, she did say she started "feeling my mortality.” Monáe mentioned the disease when talk turned to motherhood, saying that she wants to find the right time in her career and be healthy enough to have a child.

Symptoms include memory problems, physical tremors, numbness in the body, difficulty standing or walking straight, nausea and vomiting, changes in vision/hearing/speech, or a metallic taste in one's mouth. It can also be fatal.

Monáe is set to appear in the film Antebellum, from the producers of Get Out and Us. She plays the role of Veronica, a writer who's trapped in a dangerous alternate reality. The film also stars Marque Richardson II, Eric Lang, Jack Huston, Kiersey Clemons, Tongayi Chirisa, Gaboure Sidibe, Rob Aramayo, Lily Cowles, and Jena Malone. Antebellum, which was directed by "Kill Jay Z” helmers Gerard Bush and Christopher Renz, will hit theaters in April.
