“Health problems” forced Ariana Grande to cancel a scheduled concert in Vietnam last night. “My babes in Vietnam, I apologize from the bottom of my heart but I’m really dealing with some health problems at the moment,” the singer wrote on Instagram yesterday. “I came here to Vietnam, so excited to perform, my doctor won’t allow me to do the show for you tonight.” Grande didn’t provide specifics on her ailment. “I’m so, so sorry,” she added. “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.” In May, Grande suspended her Dangerous Woman world tour in the wake of the terror attack on her Manchester concert that took 22 lives. She returned to the stage for the One Love Manchester benefit concert.
