U2's front man, one of the famous men in the world, has divulged his secrets to a long lasting marriage. Speaking on a South African radio show, while on his "360 Tour", Bono said his secret is that his wife, Ali, is a "very patient missus.

"Ali is an incredible person. I'm a 'wherever I lay my hat that's my home' kind of person, but she introduced me to the concept of home," he told the Irish Daily Star.

"I didn't really feel that strongly as a kid, so I owe her that sense of belonging. I hold on to her very tightly, but you have your ups in downs . This is not Mills and Boon territory."

Bono, aka Paul Hewson and Ali met at Mouth Temple High School, Dublin in 1982. They now have four children Jordan, Memphis Eve, Elijah and John.

The ever doting father Bono spoke on the radio show about "having nervous dreams" about his children.

"I had mad dreams last night, they were nervous dreams and they were all about my kids. Those kids are amazing. Eve has a movie coming out with Sean Penn, Jordan's a bit of an activist and an amazing piano player.

"And then there's the two boys - they're just comedians. I love being around them. I have a sense that this next generation is going to be much stronger than us."

The couple now own the fashion brand Edun. It was established in 2005 with a mission to encourage trade with Africa and raise awareness of the possibilities there. Their line of clothing is currently showing at New York Fashion Week.
