With a new mega-bucks solo deal under his belt and a growing 17-million-strong fan base on Instagram – and having been a member of one of the most successful boy bands the world has ever seen – it’s almost IMPOSSIBLE to believe that One Direction’s Niall Horan turns just 23 today.

To celebrate the golden boy’s big day, we’ve rounded up our top five Niall moments…

This is one of our favourite One Direction pranks EVER. Liam posted this snap to Instagram after he and Louis stuck random items onto his Range Rover, then wrapped the entire thing up in toilet paper… just for LOLs.

Just to remind us all that he’s still one of us, Niall likes to hop on the tube every now and again...

When he hit himself in the face with a basketball

Because even if you are a global superstar, you’re still prone to the odd accident…
