Wagner will be doing the Hippy Hippy Shake, according to reports, after Simon Cowell set Beatles hits as this week's X Factor theme.
The energetic Brazilian performer will sing a mash-up of Get Back, Hippy Hippy Shake and Hey Jude, The Sun reports, as part of his hip-swinging show-stopper in tribute to the Fab Four.
Katie Waissel, who has sung for survival on the show four times, will perform Help! while rap fan Cher Lloyd is to tackle John Lennon's classic Imagine.
Cheryl Cole's other act Rebecca Ferguson will show off her big voice with Paul McCartney's famous ballad Yesterday.
Paije Richardson will perform Let It Be and favourite Matt Cardle will tackle Come Together.
Mary Byrne is to sing Something and boyband One Direction will try to tug on to the heart strings of their female fans with All You Need Is Love.
The Beatles theme coincides with the week that it was announced that the Fab Four would be finally arriving on iTunes, in a reported £500 million deal.
The X Factor performances will be available to download after Saturday night's live show, which often boosts sales of the originals.
The Beatles already have 13 albums in the iTunes Top 20, with Abbey Road the highest at number six.
