The band are rumoured to be performing at the opening of year's Games after a photo of frontman Alex Turner seemingly rehearsing at the Olympic Stadium surfaced on Twitter today (July 26).
The photo was posted by Argentinian journalist Martin John Rinaldi and re-blogged by the Arctic Monkeys US fan account with the message: "Arctic Monkeys soundchecking at the OLYMPICS. i KNEW something was up!"
It has also been suggested that the band have recorded a track especially for the event after they were spotted at a North London studio earlier this month.
It was recently announced that the group's guitarist Jamie Cook is to marry his girlfriend Katie Downes.
