David Archuleta has apologised to fans in Singapore after postponing an upcoming concert.
The Crush hitmaker was due to perform at the Hard Rock Hotel's The Coliseum venue on 19 November (11) but he has been forced to pull out of the gig due to "unforeseen circumstances".
In a post on his Twitter.com page, he writes, "Sad to inform that the scheduled Singapore show has been postponed indefinitely due to unforeseen circumstances.
"Very sorry Singapore fans... Will inform you when something in the future can possibly be done to make up for the situation."
Ticket holders are being offered a full refund.
