U2 frontman Bono has been honoured by Alicia Keys for his charity work at an Aids fundraiser in New York. The Black Ball event, which was also attended by Gwen Stefani and Sheryl Crow, is held to raise money for the Keep A Child Alive foundation which provides treatment to Aids victims in Africa. Singer Alicia Keys, who co-founded the charity, described the rocker as "an amazing man (who) works tirelessly at really having a cause and fighting for it". She adds, "He is an inspiration and single-handedly made it cool to have something to speak about." Bono was proud to accept the award but insisted he would rather be giving out the honours. He says, "Rock stars always want to do two things. They want to have fun and change the world. If they can do both at the same time, you're okay."
