5 Seconds of Summer have revealed that Harry Styles once ran into their room naked and threw fruit at them.

The Australian group have supported One Direction on tour in the past and it seems they have seen a little more than they had bargained for.

Speaking to MTV, Michael Clifford said that the band were left somewhat 'traumatised' after a nude prank from Styles.

He said: "All I remember is Harry coming in to our room, stealing all our fruit, throwing fruit at us, tipping our tables over and running away naked. It's traumatising".

5 Seconds of Summer are due to support One Direction again on their US Where We Are tour this year and the group added:

"We just waited and they asked us to come back out again. It was amazing. It's going to be so huge for them and they are going to put on an amazing show and hopefully so are we. It's going to be an amazing time."
