One Direction star Louis Tomlinson was left red-faced on Monday (23Sep13) after falling over onstage during the first gig of the band's latest Australian tour. The 20 year old was running across the stage in Adelaide when he slipped and fell on his butt during the opening night of One Direction's 24-date trek across Australia and New Zealand. Instead of bouncing back to his feet, blushing Tomlinson laughed and stretched out onstage while his bandmates splashed him with water and continued to perform their track Kiss You. His tumble comes just two weeks after he was badly injured when he was tackled to the ground during a charity soccer game in the U.K. The boyband has sold out three nights at the Adelaide Entertainment Centre, and will also perform its Take Me Home shows in Perth, Melbourne, Sydney and Brisbane in Australia, as well as Christchurch and Auckland in New Zealand.
