Dwayne Johnson Sings 'Here Comes Santa Claus' in a Big Onesie (VIDEO)

Dwayne 'The Rock' Johnson is getting in the Christmas spirit by appearing on Live With Kelly and Michael to sing "Here Comes Santa Claus". But this appearance has one significant twist: the dude is wearing a man-sized onesie for the entire segment.

In this clip, The Rock takes his surprisingly solid singing voice out for a stroll, doing his best Elvis impression for the Christmas classic, which features Santa himself coming out onstage to make it a holiday duet (all while Kelly Ripa and Michael Strahan crack up in the background). It's way more amusing than it probably has any right to be, but when you've been WWE Champion eight times, you're probably a pretty seasoned live performer.
