We all know that when it comes to a cappella songs, Pentatonix is king.

But now the three-time Grammy Award-winning group have switched things up, releasing a new original song.

Teaming up with Meghan Trainor, the quintet dropped the festive track titled 'Kid On Christmas,' to celebrate the release of their new holiday album Holidays Around The World.

Speaking about the new album, singer Kirstin Maldonado said: "We also have three originals on there, which I feel like we all love so much.

"We're all really proud of them and feel like they're our best Christmas originals yet."

The other two originals are titled 'Star on Top' and 'Prayers For This World.'
