The tearful incident took place at the Denver stop of Megan Moroney’s “Cloud 9” tour on July 28.
“This is obviously the last thing that I ever wanted to do but I am obviously extremely sick and I thought I did everything to make myself better and… I just can’t play this show tonight,” the 28-year-old explained in fan footage from the very short concert.
“I will make it up to you guys; I absolutely promise I’ll be back,” the “Am I Okay?” singer added. “But I want to give you guys the show you deserve. I’m probably gonna go cry in my dressing room now.”
Of course, Fans rallied behind the teary-eyed Moroney with a series of honky tonk hoots.
“I promise I’ll make it up to you guys like, 10 times. I love you, and I’m really sorry,” she added.
The “Wish I Didn’t” singer then stepped backstage, the concert abruptly finished.
Meanwhile, in a statement posted to her Instagram Stories, Moroney described the decision to cancel the show as “the hardest decision I’ve ever had to make.”
“I never ever will give you guys a show that is not 100% and by song 3 I knew that I was not capable of giving that to you tonight,” the “No Caller ID” singer wrote. “I’m typing this as I’m quite literally bawling my eyes out in my dressing room & it hurts me so much to disappoint you all.”
Moroney also announced she will return to Denver on Aug. 27 for a makeup show. All tickets from the July 28 show will be honored for the new date. Fans can also request a refund.
Moroney is currently on her “Cloud 9” tour, supporting her third studio album of the same name. The tour launched in late May and runs through October 1.
