It’s official. Rory McIlroy and One Direction star Niall Horan have hit bromance status.

The two Irishmen played together on Thursday at The National Golf Club of Canada, one of Canada’s premier golf courses.

Horan caddied for McIlroy at this year’s Masters Par 3 contest and played with the world No. 2 golfer at this year’s BMW PGA Championship Pro-Am.

McIlroy finished in 17th at last week’s PGA Championship after being sidelined due to injury since July 6. McIlroy, who was supplanted this week as the World No. 1 by Jordan Spieth, has captured two wins this season and is currently ranked ninth in the FedEx Cup standings heading into next week’s first FedEx Cup playoff event.

One Direction is in Toronto for their “On the Road Again Tour 2015” at the Rogers Centre on Thursday night.
