Could these two be any cuter?
This is the THIRD time Justin Bieber has joined his mate James Corden on The Late Late Show's 'Carpool Karaoke' segment.
Only this time - the two rocked out on the way to the Grammy Awards!
Donning matching white suits, Justin and James belted out Uptown Funk to get them in the mood to party.
The pair even bust out their "box" move which they created in a previous ride together.
Sing it with me now!
"Big box, little box, cardboard box! Big box, little box, cardboard box!"
