The ultimate Christmas gift

Jason Mamoa took holiday spirit to the next level during his appearance on The Kelly Clarkson Show this week.

Appearing on the show promoting his new film, Aquaman and the Lost Kingdom, the actor stuck around for a few rounds of “Sing That, Name That Tune,” a popular game Clarkson plays with her guests. Hosted by audience hype-man, Rubin, the game tested Kelly and Jason’s knowledge of Christmas songs as they had to guess the song the house band was playing by singing it in front of the studio audience — bonus points for enthusiasm and correct lyrics.

While Clarkson dominated in the beginning, earning points for “Deck the Halls” and “Jingle Bells,” Jason found his groove with song number three, “Hark! The Herald Angels Sing,” tying the pair as they went into the final round.

Both recognized the final song, “We Wish You A Merry Christmas,” at the same time and just before Rubin was going to name Clarkson the winner, Mamoa put his hand on Rubin’s shoulder “scaring” him into naming Mamoa the winner.

A hyped-up Jason celebrated his win by ripping off his pea-coat and running around the audience in a revealing undershirt that showed off his world-famous muscles. Not a bad Christmas gift if you ask us.
