It seems like just yesterday that the baby-faced One Direction boys auditioned for The X Factor, but they've done a lot of growing up since then - especially Niall Horan.
The Irish cutie - who's currently causing chaos in the States with his 1D band mates - has well and truly gone from being a boy to a man.
'Im a big boy now, and i need a shave,' Tweeted Niall, 18, to his 1,672,693 followers.
And unsurprisingly, the singer's revelation sent the Twitterverse into a frenzy with many fans trying to get #NiallNeedAShave trending.
Aww, we love seeing 1D mature - just don't go wearing your granddad's slippers and listening to classical music just yet, Niall!
