Forget the Harlem Shake, Gangham Style and even the Funky Chicken, the new dance craze is 'The Windmill' as demonstrated by Ant and Dec in performances of their No 1 hit 'Let's Get Ready To Rhumble'.
Don't try and pretend like you haven't been trying to perfect the complicated spinning dance move in your living room...
But one person who has mastered the tricky step is Xtra Factor host Caroline Flack, who then promptly uploaded a video to Twitter to show off her impressive moves.
And one of half of the duo - none other than Declan Donnelly - was very impressed with Cazza's effort, tweeting the host: "hahaha! U got it! D x"
To which Cazza replied: "@antanddec it's the most fun . Well done for a fab series x"
Ending the showbiz love-in, Dec wrote back: "@carolineflack1 Thanks lovely, we had a ball. Hope all's good. D x"
Right, that's it... We're off to practice again. How does it go again guys?
