Justin Bieber arrives at 102.7 KIIS FM's Wango Tango held at StubHub Center on May 9, 2015 in Los Angeles, California.  

Justin Bieber wasn't scheduled to be the musical guest on The Late Late Show with James Corden (that was his pal Tori Kelly), but he still managed to make some sweet music during Tuesday night's (May 12) show.

Bieber appeared on the episode (almost incognito) playing the drums with the house band led by Reggie Watts. As they played the show off and the closing credits rolled, there was Bieber behind the drum kit, filling in for the night, looking all chill and flaunting his drum skills.

You can watch his cameo below, as well as Kelly's performance of her single "Nobody Love."
