The 'She Looks So Perfect' hitmaker admits he has had to make an extra effort to hang out with his old pals and be a "normal dude" when he goes back home.

He told the South China Morning Post newspaper: "You have to really pick and choose your people. You know, I think you learn how to do that as you go through this kind of thing. You also don't relate to anyone at home as much anymore.

"If you go back and try to do things with them, you really gotta make an effort. I just go back and be a normal dude, because people who you're friends with for the right reasons just stay with you."

Meanwhile, Luke's bandmate Michael Clifford previously revealed the group - which also includes Calum Hood and Ashton Irwin - never buy each other Christmas presents as they don't want to start a "trend".

He said: "We don't want to start the trend. Because if we start the trend, then we have to do birthdays, Christmases - it's better to go without responsibility."
