In honour of last night's Super Bowl, Jimmy Fallon recruited Sam Smith, Ariana Grande, One Direction, Meghan Trainor and more for an a cappella version of Queen's 'We Are The Champions'. Watch it below.

The all-star supergroup also comprised Usher, Christina Aguilera, Blake Shelton, Carrie Underwood and The Roots - Fallon's house band.

The resulting cover contains a little too many vocal trills and loud vibrato as each star tries to gain the most attention, but it's an impressive ensemble nonetheless.

The Super Bowl took place in Phoenix, Arizona last night - and, if you're interested, was won by the New England Patriots. Katy Perry also performed at the iconic halftime show.
