OMG! One Direction to release record with Justin Bieber?
Well, if Niall Horan's latest Tweet is anything to go by, a duet between the pop superstars could be on the cards.
And judging by his followers' reactions, 1D fans would love to see the band collaborate with the 18-year-old Canadian cutie.
'Oh my...I'm going to have a heart attack,' says one.
Another adds: 'This makes my life!'
We so hope this is going to happen. (Well, some of us do, anyway.)
