Singing wannabe Rylan Clark managed to hit a bum note as he celebrated not getting the axe from The X Factor on Sunday night - by flashing his bottom in a London street.
The flamboyant 23-year-old avoided getting the boot by belting out a medley of Back for Good, Groove Is in the Heart, Gangnam Style and Pump Up the Jam - and he marked his success by heading out in the capital with fellow contestant Lucy Spraggan.
The pair went to the G-A-Y nightclub and stayed out until 4am - when they were caught on camera causing chaos.
The singers appeared to play fight, with Lucy falling into a pile of bricks, before they went on to attempt to pull off wipers from a nearby bus.
Rylan pulled his trousers down and flashed his bum, prompting Lucy to cup his privates to stop him revealing all as he yelled: "I'm a streaker."
Lucy then carried Rylan into their hotel - but their antics failed to impress staff.
An onlooker told The Sun: "They were absolutely wasted. She hit him on the head with a cleaning sign then he dumped her on a pile of bricks, where she got stuck. Next they stopped the bus, but show staff caught up and dragged them back to the hotel."
