Ariana Grande has canceled her Vietnam concert, scheduled to take place at Ho Chi Minh City's Quan Khu 7 Stadium Wednesday night (Aug. 23), due to an unspecified health issue. The singer revealed the news via an Instagram story earlier in the day.

"My babes in Vietnam, I apologize from the bottom of my heart but I'm really dealing with some health problems at the moment. I came here to Vietnam, so excited to perform," Grande wrote. "My doctor won't allow me to do the show for you tonight."

"I'm so so sorry. There is nothing I hate to do more than to do this but I promise to make it up to you in the future. I love you and thank you for understanding," she said.

Although the Instagram story is not able to be embedded, you can see a screenshot of her note captured by a fan below.

Grande's next tour date is on Aug. 26 in Beijing, China. Her upcoming tour plans also include stops in New Zealand, Australia, Singapore and Taiwan.
