NEW YORK -  Rihanna never went to college but the R&B superstar voiced delight as she was presented an award by Harvard University for her humanitarian work. “So I made it to Harvard! Never thought I would be able to say that in my life, but it feels good,” a beaming Rihanna said to students’ cheers at the prestigious US university Tuesday evening. Harvard named the 29-year-old singer its Humanitarian of the Year, pointing to her projects that include an advanced center to treat breast cancer in her native Barbados and support for girls’ education around the developing world.
