U2 frontman Bono (62) has been in a relationship with his wife Ali Hewson (61) for more than 40 years, whom he met at school when he was twelve. The two have four adult children. In a rare interview with The New Yorker magazine, the musician opened up about the secret of his decades-long love. “It’s a big madness with us,” says Bono. It has something to do with the knowledge that you are fighting against all odds together.

“But if you seriously ask me, I would say that sometimes friendship can trump romantic love. And friendship is what Ali and I have.” If you have both, then that is something special. Bono stressed that that doesn’t mean every day is a wonderful day. Even if it was sometimes difficult in the four decades, he and his wife always stuck to this connection.

“Any time one of us got lost, the other was there to bring the other home and I’m very grateful for that,” says Bono. In general, 40 is a special number for him, which he already realized on his 40th birthday. At that time, he and his wife swore to each other: “Let’s not screw this up now.”
