As the boy band, that consists of Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson, were performing 'Kiss You', Tomlinson ran across the stage and slipped over.
The group did not stop their performance, although two of his bandmates checked if he was fine.

After the show, Horan tweeted, "Yessss adelaide ! One of the loudest crowds ever! What a night ! That's it! Take Me Home Tonight is back on the road.
