OMG!! We were already obsessed with Justin Bieber and David Guetta's new collab "2U" but this video just sealed the deal. Conor Maynard and Olly Murs mashed up the instrumental of the song with literally every song ever. They sang Passenger's "Let Her Go", Taylor Swift's "I Knew You Were Trouble", and even R Kelly's "Ignition (Remix)" with "2U" as the backup track. This is definitely worth the watch!!
