One Direction singer Harry Styles has reportedly been given a talking to by their management team.

The teenager has allegedly been spending time apart from his bandmates and partying with DJ Nick Grimshaw and other stars.

When on tour the lads are tight, but their team are worried that Harry is starting to move away from Liam Payne, Niall Horan, Zayn Malik and Louis Tomlinson.

The management’s fears were increased when Styles decided to move into his own apartment, after sharing with Louis.

A source told Heat magazine: “Harry has been given a dressing down in recent weeks.

“It was noted that he’d broken away from the band a bit and, with their American tour in progress and dates in Australia to follow, the boys really need to be acting like a unit.”

One Direction have enjoyed international success and their US tour is going well.

The insider added: “The boys are set to become the biggest boyband in the world this year and it’s no time for individual egos.

“This was made very clear to Harry. He was told he needs to start being a team player and that’s that.”
