The pair party at G-A-Y

The X Factor finalist Rylan Clark enjoyed a crazy night out in London with fellow contestant Lucy Spraggan on Sunday night after making it through to next week’s show.

The pair were snapped play fighting and messing around with the windscreen wipers on a bus before Rylan exposed his bare bum by pulling his pants down.

‘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,’ an onlooker tells The Sun.

‘Next they stopped the bus, but show staff caught up and dragged them back to the hotel.’

The pair had earlier celebrated their success at London club G-A-Y, where Rylan, 23, was spotted kissing and dancing with a transvestite model on the dance floor.

It seems Lucy, 21, was suffering yesterday after her and Rylan‘s evening out.

‘Been in the studio since 10am. I don’t feel very well… @RylanClark, you’re a very bad man,’ Tweeted Lucy.
