Ariana Grande has sad news for her fans in Portugal.

In a Saturday Instagram post, the 22-year-old singer announced that she cancelled her performance at Lisbon’s Rock in Rio festival (running from May 19-May 29).

“I’ve literally been crying over this for an hour,” Grande wrote in the post, captioning the photo with a simple sad face. “I have a throat & sinus infection & my doctors have advised me not to sing for a few days.”

However, the “Focus” singer gave her fans a bit of hope.

“I promise to make it up to you, and give you the best show I’m capable of when I return,” she continued. “Again, I’m so sorry to the babes who were coming to see me. I love you with all my heart.”

The cancellation comes just days after Grande showed off her powerful vocals at the 2016 Billboard Music Awards, performing “Dangerous Woman” and “Into You.”

Grande put her vocals to work again days later on the season finale of The Voice, singing with Christina Aguilera.
