7 photos of Rory McIlroy and his new BFF Niall Horan teeing it up at the BMW PGA Pro-Am

This is getting to the point of an official bromance. Rory McIlroy had One Direction star Niall Horan caddie for him at this year's Masters Par 3 Contest, which surely upped Augusta National's following by the "teenie bopper" generation for the week.

Now Rory and Niall are teeing it up at the BMW PGA Championship at Wentworth, one of the biggest events on the European Tour schedule. Augusta and Wentworth -- that's a pretty good one-two for this duo.

Joining these two Irish buddies on Wednesday at Wentworth were former Manchester United soccer stars Paul Scholes and Phil Neville.

After their round, the European Tour had Rory ask Niall a bunch of questions from social media for a solid #AskNiall segment. Niall said he'd choose Frank Sinatra as the singer he'd most like to play golf with (great choice!), he's shot a 79 before (solid), and had some intelligent thoughts on why people think golf is boring (you have to play it!). Watch the full segment below.

We could imagine soccer legend Paul Scholes and Horan laughing to each other, saying: "I wonder if people realize how famous we are out here at the golf course."

What do you think Rory's saying to Niall's caddie? "Not another skulled chip shot. Man, he's really cramping my style. I'm not gonna be able to keep watching this.

This pro-am, of course, pales in comparison to the type of fun it looks like Niall had at the Billboard Music Awards after-party with Taylor Swift, Calvin Harris and Ed Sheeran. Jet-setting to tear it up on both continents. That's a world-famous musician move. Well done, Niall.
