Keen-eyed fans spotted Biebs on the drum kit for the closing of The Late Late Show this week.

We always knew Justin Bieber was cool as a cucumber, but we didn’t know he was THIS cool.

At the close of The Late Late Show with James Corden this week, keen-eyed fans realised that the house band’s drummer had been replaced with none other than Biebs himself!

Yep, despite being unannounced throughout the show, Bieber was rocking out on a drum kit, showing off his musical skills, with the only acknowledgement being a cheeky bow at the end of the show.

Hit play on the video above to see Justin’s skills in action, this boy can SERIOUSLY lay down a beat.
