Halsey left the 2022 Grammy Awards early on Sunday as she was "not feeling super well".
The Without Me hitmaker - who uses both she/her and they/them pronouns - announced on Saturday that they would be attending the music ceremony in Las Vegas three days after having an operation to treat their endometriosis.
After making a brief appearance on the red carpet and inside the show, they decided to exit the prizegiving early to prioritise their health.
"Not feeling super well so I left early," the star shared on their Instagram Stories. "Had to see BTS tho (sic). Going to get pasta and sleep. Thanks for everything luv u all."
In their original message, the 27-year-old asked anyone who saw them at the Grammys to "be gentle" as they were feeling fragile.
"The last time I attended the Grammys was 2017 and it was 3 days after I had my first Endometriosis surgery. I walked the carpet with my stitches still in," the singer wrote. "As luck would have it, I'm attending tomorrow for the first time in years and I had surgery again (you guessed it) 3 days ago. Only posting this to say, if you see me be gentle lol I'm fragile. Fragile but excited."
Halsey was nominated for Best Alternative Music Album for If I Can't Have Love, I Want Power but was beaten by St. Vincent with Daddy's Home.
