Justin Bieber was back in the passenger seat of James Corden's car for a special post-GRAMMYs edition of "Carpool Karaoke" on The Late Late Show.
Seeing as this is the 21-year-old heatthrob's third time participating in the segment, the two decided to sing Bruno Mars' "Uptown Funk" rather than one of Bieber's hits.

The late-night host and "Sorry" singer are quite the comedic duo. When Bieber shows up wearing a tuxedo that's almost identical to Corden's, the TV personality quips, "We already looked stupid. ...We look like a pair of waiters on a cruise ship!"
Showing just how deep their friendship goes, Bieber even helps Corden moisturize his T-zones.
