The Alfred Dunhill Links Championship is a unique tournament that sees some of the world's top professional golfers team up with amateurs to play rounds at St Andrews, Carnoustie and Kingsbarns golf courses.
Each partnership play a round at each of the courses before the top 60 professionals and the leading 20 pro-am teams progress to a final round at the home of golf - the iconic St Andrews’ Old Course.
Amongst the amateurs are a liberal smattering of famous faces from the worlds of music, film, media and sport - relishing the chance to swing alongside the pros.
The tournament starts today (Thursday, October 1) and all eyes will be on Scottish player Robert MacIntyre, who triumphed at his home tournament 12 months ago and will be looking for a successful defence.
Here are 13 pictures of the celebs and golfers warming up during a practice round yesterday (Wednesday, September 30).
