In a collaboration that's sure to cause millions of fangirls to scream across the world, One Direction star Niall revealed the group were in the studio this week.
He wrote on Twitter: "In the studio with @justinbieber last night, its gonna sound great! [sic]"
But the Irish singer refused to give anything more away!
Meanwhile bandmate Liam tweeted: "Got first listen to justin biebers new album yesterday wowww big songs!!! Its gunna be a smash...Except the unexpected 😮 [sic]"
While Justin tweeted the pair to say: "thanks buddy. good chillin with u guys. [sic]"
Justin's manager Scooter Bruan previously revealed that a duet between the six teenager performers could be on the cards.
He said: "[Justin] likes them and thinks they are good dudes. All people of that generation should be there to help each other."
But while all this was going on, Harry Styles was having a much bigger problem.
