Matt Bellamy says walking rather than songwriting has helped him get over his split from Kate Hudson.

The Muse frontman has confessed he turned to countryside strolls after ending his four year romance with the 36-year-old actress - who is the mother of his three-year-old son Bingham - instead of expressing himself through his music.

Matt, 36 - who grew up in Devon - added he has long enjoyed roaming through unpopulated areas and even participated in ''letter-boxing'', an outdoor activity which combines orienteering with puzzle solving, in his younger years.

He said: ''I aways go for walks in the countryside. The South Devon countryside... I used to go letter-boxing actually.''

The 'Supermassive Black Hole' hitmaker is looking forward to the release of the band's upcoming album 'Drones' and insists the split has had no obvious impact on the record.

He told NME magazine: ''It's difficult for me to pinpoint anything on the album specifically about that. Except that when someone suddenly finds themselves outside of a relationship, they ponder things, they think over the points in their lives when they think things didn't go the way they expected them to.

''It's the fact that I reconnected with all the points in my life where I felt alone or outside.''

The comments mark the first time the musician has spoken publicly of their break up since tweeting a thank you message following the release of the couple's official statement last December.

A representative for the actress said at the time: ''Kate and Matt have been separated for some time now. Despite this, they remain very close friends and committed co-parents.''

Following up the message, he tweeted: ''Love all of you guys! We're both very happy, it's for the best. Thanks for your kind words. Now about that new album... (sic)''
