Halsey is having a touring nightmare.

The “Bad At Love” singer revealed they are recovering from a nasty case of food poisoning while in the U.K. for the Reading and Leeds festival.

“No idea how I’m still alive after my Leeds set,” Halsey wrote on their Instagram Stories on Aug. 27. I have horrible food poisoning! It began yesterday afternoon at 2 p.m. and I managed to make it onto the stage after the help of the festival medical staff !).”

Halsey explained that they have played shows under some “messed up conditions” in the past, but this was “the worst in recent memory.”

“Felt like I was on Jupiter the whole time,” they continued. Thanks for being so kind and allowing me to basically do anything just to get through the set. You would’ve been an amazing crowd, regardless of the circumstances. It’s time to go now for Reading tomorrow.
