Watch: Justin Bieber Is James Corden's Carpool Karaoke BFF

We can't get enough of James Corden's epic Carpool Karaoke sessions. Corden decided to film a special edition of the famous singalong segment of his show, especially for the Grammys. And he picked up his Carpool BFF Justin Bieber for the occasion.

This was the third time the Sorry singer joined Corden for Carpool Karaoke, but this outing was distinctively shorter. The main highlight was seeing Bieber groove to?Mark Ronson and Bruno Mars's Uptown Funk, which took home Record of the Year.

Corden and Bieber then spent most of the clip going through their Grammy swag bags - where the host was disappointed to learn there's somewhat of a tiered system when it comes to goody-bag distribution. Yes, only major celebrities get the good stuff.

Bieber's bag contained luxury items galore: a Rolex watch, a diamond bracelet, a mini iPad and a private plane trip to the Maldives. However Corden's included budget-friendly products, including a candle, lip balm, a map of Los Angeles and a Danielle Steel novel (possibly the best item of the lot).


The matching suits, Bieber's facial expressions and 'box hand' dancing make this another must-see clip:
