NEW YORK - Rihanna may be best known as an R&B superstar, but on Wednesday she was named the 2017 Harvard University Humanitarian of the Year for her charity work. The 29-year-old singer from Barbados will be given the award in person on campus on February 28, the university announced. “Rihanna has charitably built a state-of-the-art center for oncology and nuclear medicine to diagnose and treat breast cancer at the Queen Elizabeth Hospital in Bridgetown, Barbados,” Harvard Foundation director S. Allen Counter said.
