Do you smell what The Rock is cooking? It's probably the scent of Christmas cookies.
Dwayne "The Rock" Johnson showed up in a snowflake onesie for a little "Christmas karaoke" on Live with Kelly and Michael -- and his singing voice is quite impressive.
Performing "Here Comes Santa Claus," the actor even "slapped a little more Elvis" on the classic carol.
Johnson even had a surprise guest mid-performance. That's right, Santa Claus himself showed up!
What do you think of The Rock's singing skills?
