Niall Horan and Rory McIlroy hit the green

One Direction's Niall Horan has done his caddying duty for golfing ace Rory McIlroy at The Masters par 3 contest - but he fluffed his lines when he got his chance to swing the club himself.

Last year McIlroy's caddy was none other than a pink haired Caroline Wozniacki, but his now ex-girlfriend was nowhere to be seen as 1D star Horan took centre stage.

While Niall looked the part in his Augusta caddying gear, he dumped a ball into the water when McIlroy handed him the chance to show his worth on one of the par 3 holes.

He then embarrassingly fell over during an interview with Sky Sports' presenter Kirsty Gallagher, but he seemed to enjoy his day, which included meeting the great Tiger Woods.

Beside celebrity appearances, the big question on everyone's lips is weather or not Rory McIlroy can become only the sixth player in history to complete the career grand slam by winning his first green jacket and third major in a row.

McIlroy is the favourite at this year's competition despite recording just one top 10 in six previous appearances, his tie for eighth last year coming after the embarrassment of being outscored by his marker, Augusta member Jeff Knox, in the third round.

The world number one could have made the Masters his first major title after taking a four-shot lead into the final round in 2011, only to collapse to a closing 80 that featured a triple-bogey seven on the 10th - where his hooked drive found a part of the course never seen before - and a four-putt on the famous par-three 12th.

Remarkably he bounced back two months later to win the US Open by eight shots and believes his "unravelling" at Augusta was the most important day of his career.

By winning the 2012 US PGA and the Open at Hoylake last year the 25-year-old completed three legs of the career grand slam, with a second PGA title at Valhalla the icing on the cake as it proved he could win after a back-nine battle in the final round.
