Sorry, but, this is GAS!
It looks like Niall Horan and Justin Bieber had a lads night out over the weekend.
Niall was seen on Justin Bieber's Instagram story last night, and Justin couldn't get enough of Niall's face.
He posted two videos of Niall where he kept zooming in on his face, shouting 'let me see that mug of yours' but the zooming didn't stop there. Oh no.
In case you missed it, Niall's album cover for Flicker is a zoom in on his face, and Justin thinks this is gas because he's slagged him off by Instagraming a picture of his own face zoomed in.
Seems like it was all friendly banter though, as Niall commented loads of laughing emojis under it, followed by 'arsehole.'
