One D's Niall Horan has revealed that the group's next album is set to be "more edgy".
Fans of the lads are eagerly awaiting their next musical offering, which is due out later this year.
Speaking to Carson Daly from NBC's Today Show, Horan also admitted that he still finds the group's success overwhelming.
He said: "I've noticed it a lot on this tour. You know, when you step out on stage at these amazing stadiums.
"We end up spending the first 20 minutes looking at each other going, 'Wow, look where we are'. It's unbelievable what has happened."
