When WWE wrestler and movie hunk Dwayne Johnson sang Here Comes Santa Claus in a onesie last year we were impressed with the big man's ability to laugh at himself.

And now he's proved that his sense of fun is even bigger than his impressive biceps by taking part in a new TV show where celebs do battle by lip-syncing to pop tracks.

A clip of the muscleman leaping up and down as he tackled Taylor Swift's pop hit Shake It Off has been shared on his Instagram.

He wrote: "#LipSyncBattle OF ALL Lip Sync Battles... Channelin' my inner @taylorswift And comin' to take the title from @jimmyfallon #IJustShakeItOffBaby #RockVsFallon #Spike APRIL 2nd."

The show is a spin-off from the hugely popular lip-sync battle segment on Jimmy Fallon's chat show in the US - although the new series will be hosted by hip-hop legend LL Cool J - setting the bar high for anyone considering rapping!

And from The Rock's caption it sounds like he might be taking on Fallon himself in the debut episode.

The 42-year-old star will also be flexing his comedy muscles when he hosts Saturday Night Live on 28 March.
