Bono, whose real name is Paul Hewson, was born in Dublin, Ireland.
His musical career started at the age of 16 when he formed a little rock band called U2 along with friend David Evans - better known as guitarist "The Edge" - while at school.
Now the band is one of the biggest in the world - winning 22 Grammy Awards - more than any other group - and selling more than 150 million records.
Bono is also known for his humanitarian work.
His campaigns to fight poverty and AIDS earned him a Nobel Peace Prize nomination in 2009.
And while the singer has been criticised for his activism, he has always stood his ground.
"My name is Bono, and I'm a rock star. And where would we be without rock stars and their delusions of grandeur", said Bono.
Bono will again take centre stage when U2 headline Glastonbury in June.
