London: Singer Alicia Keys paid tributes to chat show queen Oprah Winfrey for her philanthropic efforts.
Keys honoured Winfrey at her Keep a Child Alive Black Ball Redux held Thursday.
The "Girl on Fire" hitmaker, whose charity assists those affected by HIV and AIDS in Africa and India, paid tribute to the talk show host for her philanthropic efforts, including her school, The Oprah Winfrey Leadership Academy for Girls in South Africa.
"It`s a universal truth, Oprah makes change happen," a website has quoted Keys as saying.
Before Winfrey took to the stage, a video was played on screen explaining the launch of the school and also detailing the 58-year-old`s own struggles travelling with maids from the inner city out to the suburbs to attend a better high school.
"When I look at African girls I see myself. I continue to work for them to have the same opportunities that I have," said Winfrey.
