Camila Cabellois canceling a performance onTaylor Swift‘s Reputation Stadium Tour after falling ill.

The “Havana” singer, 21, told her fans Monday night on Twitter that she was canceling her performance in Seattle, Washington after she went to the hospital following her performance on Sunday night’s 2018Billboard Music Awards.

“So yesterday after my performance at the billboards, I was feeling really sick and ended up in the hospital to get checked out,” Cabello tweeted.

“They ran a lot of tests and everything is fine, but the diagnosis was basically dehydration and I also have a low grade fever — the doctors have told me I really have to get rest otherwise I won’t get better — so unfortunately I won’t be able to perform my set during the Reputation tour in Seattle tomorrow.”

“I’m so sorry to let you guys down and I promise I will make it up as soon as I can! I guess sometimes I just push myself too hard and I promise I’m gonna take better care of myself,” Cabello continued.
