The TV star is the latest celeb to take part in the Undercover segment of the ITV show, which sees stars getting tricked by presenters Ant and Dec.
A teaser released ahead of Saturday’s episode (1 April) saw the hosts in fits as Rylan stumbled thought a series of hilarious challenges for a gag based around Eurovision, where he will be one of the presenters.
“He loves Eurovision – this is going to be awful!” exclaimed Ant with a gleeful smile, before Rylan was seen struggling to gain access to the building and looking utterly baffled as a director asked him to say the word “pickle”.
The star was also given a line in another language – and appeared to be unaware that he was asking if he smelled like cheese – and had to ride on a person in a green body-suit who was pulling themselves along on a skateboard.
Meanwhile, Ant and Dec appeared to be posing as Eurovision contestants themselves as the brief clip showed them donning huge black and white bird suits that were then spotted on stage behind some singers.
Rylan looked horrified as the prank appeared to dawn on him, clapping his hands to his face and groaning: “Oh my God… I rode that man!”
Ant and Dec also teased the gag on Twitter, posting: "For our last Undercover of the series we're going BIG!"
"B*******," Rylan quipped back.
The episode will also see Rob Beckett as guest announcer, while Busted will be performing the End Of The Show Show.
It will also include the penultimate episode of Ant and Dec’s mini-TV show Murder At Bigwig Manor.
The show airs live on Saturday night at 7pm on ITV1 and ITVX.
