Kasabian have announced a last-minute cancellation to their Belfast show due to "illness".
The group shared the news minutes before they were due to perform at Customs House on Tuesday night and only a day after tweeting that they were "buzzing" for the show.
They are also due to hit the stage at the Reading and Leeds Festivals at the weekend.
A message on the Leicester-based band's official Twitter account read: "It is with great regret, due to illness, we cannot perform at Customs House Belfast tonight. Kasabian."

Ticket-holders, some of whom had been queuing through the day during wet weather to secure a decent spot for the performance, took to Twitter to share their frustration.
Ryan Scott replied: "10 mins before your supposed to come on! I've been paying 5 quid pints for 2 hours!"
Vealey added: "Why wait until 20:50 to tell the fans... we've been stood in the rain for nearly 3 hours!"
Even fans who had not planned to attend the show shared their thoughts, with Peter Riding commenting: "Your loyal traveling fans need some sort of compensation for this . I would be fuming if it was me."
Among others demanding a refund, one wrote: "Are you serious?? Just flew from Edinburgh to see you's!!!! Are you goin to refund flight and hotel money !!!!! No more my heros!!!!"
The band's representation has been contacted for comment.
