Golfer Lexi Thompson has paid her respects to Muhammad Ali, who would have been 75 today.
Thompson partnered with Red Bull to recreate iconic photos of 'The Greatest' posing underwater.
21-year-old Thompson - a star on the LPGA Tour - also gave the photo a special golfing twist, posing underwater with her driver.
Ali died in June last year at the age of 74.
He won 56 of his 61 professional boxing fights, 37 by knockout.
