One Direction star caddies for McIlroy

Niall Horan, a member of pop group One Direction, says it is a "honour" to caddie for Rory McIlroy in the Par 3 Contest at the Masters in Augusta.

Horan joined up with his friend and world number one McIlroy for the pre-tournament event on Wednesday.

McIlroy would complete a career Grand Slam of golf's four majors if he won the Masters.
