Liam Gallagher was forced to cut a festival show short after a chest infection made it difficult for him to breath on stage.
Video footage recorded by fans at Lollapalooza Festival in Santiago, Chile, showed him explaining that his voice sounded "f**king horrific" before leaving the stage.
"My voice is absolutely smashed. I'm not just going to stand here all night screaming out for everybody sounding f**king horrific," he says. "I'm very sorry I can't sing the tunes."
His announcement was met by boos from disappointed fans, to which he said: "If you ain't gonna have fun, I'm wasting my time."
A statement was later released on Gallagher's Twitter account which explained he had been having trouble breathing due to a chest infection.
"Liam was diagnosed with a sinus, ear and nose infection after a European show a few weeks ago which has led to a chest infection. He has been continuing to perform and trying to push through it but unfortunately today he was finding it hard breathing on stage and wasn't able to continue the set.
"Liam is severely disappointed and upset that he couldn't finish the show and wants to apologise to everyone who came out to see him tonight. He promises to reschedule a gig in Santiago as soon as possible."
