The singer, who releases his new record Write it on Your Skin next month, also said becoming a father in the last year has made his music "stronger".
Watch what he had to say in an exclusive interview below:
He admitted: "We've done something different to what we've done before. We've obviously kept all the best bits but we've kind of shaken it up a bit.
"I'm still trying to work out whether being a dad has changed my writing. It's changed part of my brain, but I think all it has done is made things stronger that were already there."
Write it on Your Skin marks the star's third studio album, following 2009's gold-selling Rebuilt By Humans.
Watch the music video for his new single 'Clouds' below. The LP follows on July 9.
