Justin Bieber and James Corden got to work serving up grilled cheese sandwiches (with bacon!) and fish tacos from their "Yummy" food truck while filming a bit for the Late Late Show. Bieber and Corden made meals for well over 100 people but spent just as much time dancing as they did cooking! The stunt was good a good cause, with proceeds from the food truck are going to the L.A. Food Bank.

So on to the dancing ... Justin showed James Corden some moves -- is Corden aiming to be a backup dancer for Biebs??? It could happen! Justin's been putting in the work at the dance studio for months ahead of his 2020 tour so he probably has plenty of new moves to pass on.
