They're not just pop stars.
Niall Horan and Justin Timberlake might be known for being part of two of the world's biggest boy bands but they also share a secret hobby - both are avid golfers.
Timberlake has his very own PGA Tour event named after him and Horan has made a name for himself in the golfing world recently, caddying for Rory Mcllroy and recently playing the iconic Augusta National course:
Can't believe Im saying this as its a life long dream of mine but I had the absolute honour of playing 46 holes over the last two days at Augusta National . An experience I will never ever forget . This is a picture of my second shot into 13 , my favourite hole in golf , which I had par on all 3 times I played it I'd like to add... Now I really can't wait for @drivechipandputt Sunday . @themasters
Yesterday, the two singers surprised young players by appearing at the Drive, Chip and Putt Championship.
