American golfer Justin Thomas grabbed headlines on Thursday - and it had nothing to do with his performance in the pro-am round of this year's Wells Fargo Championship.

Well, almost nothing…

The world's number two-ranked player was filmed helping a golf-mad fan pop the big question to his partner, in what is arguably one of the most elaborate and creative marriage proposals yet.

In the video, the fan Sean Powell can be seen signalling Thomas over at the end of his round at Quail Hollow.

With Powell's girlfriend Andrea Cota watching in growing disbelief, Thomas casually strolls over and starts making small talk with Powell.

Last year's PGA Championship winner is introduced to Cota and he proceeds to give her a golf ball from his pocket.

Cota's gets the first inkling that this was far from a chance meeting when she notices the question "Will You?" scribbled on the ball.

Cota turns around to see Powell on one knee with a ring. After an excited "Yes!" Thomas jpoins the couple for a couple of pictures.

Powell's engagement plan reportedly hatched months before when he sent Thomas a direct message on Instagram – and he responded within minutes.

"I wanted to do this and was like, 'Well, I'm going to go for my favorite golfer,' " Powell told the New York Post.

"I sent him a message and about five minutes later he responded back and said, 'I'll help you out.' So I was scheming with him and [the PGA Tour] for two months on how we were going to set it up and do it. I couldn't be more happy with the outcome.''

The couple, from From Sioux Falls in South Dakota, got to spend some time with Thomas after the round.

The 25-year-old has some decent form heading into the Wells Fargo, having finished tied 17th at the Masters in April.

And yes, he has been invited to the wedding.

Thanks for letting me be a part of it! Y’all seem like great people and wish you nothing but the best in your future together 👌🏽👌🏽 https://t.co/1xzzdjd3zY
