Rihanna has been honoured for having done charity work in Bridgetown, Barbados, by building a "state-of- the-art centre for oncology and nuclear medicine" for breast cancer patients at Queen Elizabeth Hospital.

"She has also created the Clara and Lionel Foundation Scholarship Program [named for her grandmother and grandfather] for students attending college in the US from Caribbean countries, and supports the Global Partnership for Education and Global Citizen Project, a multiyear campaign that will provide children with access to education in over 60 developing countries, giving priority to girls and those affected by lack of access to education in the world today," S Allen Counter, the Harvard Foundation's director, said in a statement.
