"It was amazing and scary. I'm a pretty private person, so the exposure made me uncomfortable, but you adapt, and I've had such great fun with it.
"If I were to advise anyone, rather than pursue fame and fortune, I'd recommend pursing anonymity and fortune. Hell, maybe just pursue happiness," Blunt says.
"I've just released my fifth album, and am on my fifth world tour - making the music, and playing it live has been an amazing experience.
"I took (Ed) skiing last year, which he'd never done before, so I taught him how to ski by day, and he taught me how to write songs by night. The song we wrote is called 'Make Me Better' and it's on my new album, 'The Afterlove'," he says.
