Dwayne "The Rock" Johnson shows off his festive side on the set of "LIVE with Kelly and Michael" and took part in a Christmas karaoke showdown while wearing a Christmas onesie, Full-Time Whistle reported.

Johnson joined show hosts Kelly Ripa and Michael Strahan in a trio performance of "Here Comes Santa Claus" while in a grey onesie and a Santa hat on his head.

The 42-year-old even noted his festive attire, pausing in between his song number and joking "I'm in a onesie," according to Daily Mail.

He also didn't pass up the chance to add in an Elvis Presley impersonation, and said, "I think we need to slap a little more Elvis on this." He then sang on with a tune inspired by the late singer and even added in the famous leg tremble in his performance, as Ripa and Strahan cheered him on. At one point, Johnson was also joined by Father Christmas for a duet just in time for a grand finale.

The actor has tweeted about the experience, saying, "Here comes Santa Claus, here comes Santa Claus.. #KaraokeKING @KellyandMichael #RealGsWearOnesies."

He also tweeted, "I'm bringing home the gold for us. #ElvisWouldBeProud #SantaRock #InAOnesie."

This is not the first time Johnson showed off his humorous and festive side as he also posted a Christmas card on his twitter and Instagram in celebration of the holidays, according to News.

Johnson posted a photo of himself and captioned it with the words, "Happy Holidays! Love always, #TheBuffLesbians #OurMistleToeRocks #WTF."
