When James Corden is stuck in traffic, and needs an extra passenger in order to use the coveted carpool lane, the Late Late Show host has some pretty great friends he can call to help him out of that jam.
This week, Corden reunited with a previous carpool passenger: Justin Bieber.
Together, Corden and Bieber drove through the streets of Los Angeles (you know, where all the carpool lanes are?) singing some of the pop stars greatest hits, and a few of his new singles.
Kicking it off with Bieber's early hit "Never Say Never," the duo continued on through his recent song "What Do You Mean?" and then took on a few other artists' beloved tunes, like Kanye West's "Stronger" and Alanis Morissette's "Ironic."
Outside of singing their hearts out like no one was watching, Bieber and Corden also enjoyed a John Hughes-esque shopping excursion, dealt with swarms of paparazzi, and talked about Bieber's recent nude photo scandal.
"I, along with the rest of the world, got to see what I like to call The Whole Bieber the other day," Corden ventured. "How did that feel when that picture just went everywhere?"
"Well it definitely felt, like, really invasive," Bieber admitted earnestly. "It's funny to joke about it now, because what else can you do? You gotta just laugh about it."
Although the 21-year-old singer quickly admitted that his biggest disappointment about the photo was the "shrinkage" he suffered from just getting out of the water.
