One D to collab with the Biebs?
Best. Duet. Ever!
Hold the phone, One Direction and Justin Bieber on one track?! 'Scuse us while we pick ourselves up off the floor, but from the look of a recent tweet from Niall Horan, it looks like one of the best duets EVER could be happening! He tweeted: "in the studio with our boy @justinbieber last night , its gona sound great!" Woop! Reaaally hoping that this isn't like the wishes on a birthday cake sitch and that even though we've told you it'll still come true. Crossing EVERYTHING! What do you think of them teaming up?
