But just when Horan enthusiasts were starting to suspect that all hope was lost, he's been found over in Las Vegas enjoying a spot of UFC Fighting and looking possibly fitter than ever before.
THE GLASSES. THE SUIT. THE TAN. THE HAIR. Help.
Having toured here, there and everywhere around Asia with his little red backpack, Nialler has headed West for a trip to Vegas, and last night he was in the crowd for UFC196.
Here he is having a chat with BT Sport about things that we don't understand – but it's okay because we would have been distracted by his accent and messy hair anyway.
And here he is talking about some other stuff that we can't decipher, but you can just enjoy him buttoning his suit jacket instead if you're anything like us.
This video should probably be illegal.
"WHERE WE GOING TODAY MARK?" Niall asks as they take their seat at the UFC.
"I don't know Niall, I'm so hypnotised by your chest hair that nothing else matters in the world," he replies.
God we missed him. But if a few months away from the spotlight brings him back looking THIS unbelieveably fit, then we're kind of okay with it.
Glad to see what Niall's looking happy and hotter than a human jalapeno? Let us know with a tweet to @Sugarscape.
