The multi-chaptered "Yummy" campaign continues.

On Wednesday, Justin Bieber hopped inside a "Yummy"-themed food truck in Los Angeles to offer fans and circumstantial passersby alike a chance to score some grilled cheese sandwiches and fish tacos for merely $1 each. Per TMZ, Late Late Show host James Corden was also involved with the truckery, which makes sense given Bieber's recent hints that the two would be filming something together.

Proceeds from the truck, which featured product names that nod at previous Bieber singles, go to local food banks. According to the TMZ report, Bieber and Corden also shot some Carpool Karaoke shenanigans the same day.

"Yummy," the promo campaign for which has received its fair share of criticism, is currently at No. 10 on the Billboard Hot 100. A new album is set for release this year, as is a YouTube documentary series.
