Harry also opened up about the new album, which is believed to have been inspired by his relationship and break-up with model Camille Rowe, 33, whose voice features at the end of the track 'Cherry'.
He said: "I write from personal experience, I think a lot of people do. I think if you want your songs to be honest and connect with people, it's usually from writing honestly. It's definitely about what I was going through at the time, which is good and bad. This album for me, the times when I was sad were some of the saddest times of my life but then at the same time, the times I was happy were some of the happiest times of my life, so it's a fine line."
