When we caught the tracklist for Just Bieber’s upcoming holiday album Under The Mistletoe, we hardly expected the first single, “Mistletoe,” to be a reggae-inflected number. But that’s just what Biebz offered up during a gig in Rio de Janeiro this week. And, really, nothing sums up Christmas sparkle more than the phrase “I wanna be under the mistletoe, shorty, with you,” does it? Pucker up below. “This is the first time anywhere in the world that I’ve sang this,” Bieber tells his screaming fans. “So this is special. This is just for you.” Aw, thanks, shorty!

But wait — JB also rocked out another surprise for Rio: a surprise appearance by his girlfriend Selena Gomez. The pair performed a duet version of Selena’s hit “Who Says.”

Get a load of the kiddies singing along with every word:
