“Last night ‌was a real wake-up call for me,” the rapper wrote. “I’ve been pushing myself past my limits lately, running on empty, and my body finally said enough.”

A spokesperson for Megan Thee Stallion confirmed ​in a press release that the performer underwent a medical evaluation Tuesday night. ​Doctors concluded she was suffering from extreme exhaustion and dehydration, along ⁠with vasoconstriction and low metabolic levels.

Echoing that assessment, the 31-year-old recalled feeling as though ​she might faint while onstage.

Megan Thee Stallion is currently starring as Harold Zidler, the flamboyant ​nightclub owner, in the Broadway production—marking the first gender-swapped casting of the role.

Despite the scare, the rapper struck an optimistic tone. She told fans she plans to take one day to rest and ​recover before returning to the stage on Thursday.

“I just need a day to reset ​and take care of myself,” she wrote. “I’ll be back feeling stronger.”

She closed the post by thanking ‌her fans ⁠for their continued support, sharing a photo of herself in full costume onstage. “Thank you for always riding with me and loving me through everything,” she added.

Megan Thee Stallion is a three-time Grammy Award winner and one of the most successful rappers of her ​generation. Her 2019 breakout ​hit “Hot Girl Summer,” ⁠featuring Nicki Minaj and Ty Dolla $ign, cemented her rise to mainstream stardom. The following year, her chart-topping single “Savage” earned two Grammys ​and dominated the U.S. Billboard Hot 100.

"Moulin Rouge!" opened with Megan ​Thee Stallion ⁠in the cast on March 24. The Broadway production is based on Baz Luhrmann’s 2001 jukebox musical film of the same name, starring Nicole Kidman and Ewan McGregor.

The story centers ⁠on ​Christian, a young English poet who falls in love ​with Satine, the glittering star courtesan of the Moulin Rouge nightclub.

Megan Thee Stallion is scheduled to appear in ​the role of Harold Zidler through May 17.
