(CNN) -- It wouldn't be Christmas without a celeb in a onesie.
Dwayne "The Rock" Johnson joined "LIVE with Kelly and Michael" hosts Kelly Ripa and Michael Strahan for a little Christmas karaoke smack down on their show. The trio donned Christmas onesies and Johnson offered his version of "Here Comes Santa Claus."
The star posted a picture of his performance on Instagram with the caption "Here comes Santa Claus, here comes Santa Claus right down Santa Claus lane..." #KaraokeKING #LIVEWithKellyAndMichael #ChristmasEveShow #RealGsWearOnesies."
He wasn't the only one enjoying the festivities.
Taylor Swift had earlier posted a selfie with her adorned tree and later tweeted "My dad just gave me ten lint rollers for Christmas, not for lint but 'because you always have glitter all over you'. Great start, Swifts."
