Rihanna, the Barbadian recording superstar aka Robyn Rihanna Fenty, has gotten into the spirit of the holiday season in a big way.

The singer's Clara Lionel Foundation -- named for her now-deceased grandparents Clara and Lionel Brathwaite -- recently contributed three pieces of equipment worth more than $1.75 million to the Queen Elizabeth Hospital Barbados, according to StabroekNews.com in Georgetown, Guyana.

The hospital responded by renaming its radiotherapy operation the Clara Brathwaite Center for Oncology and Nuclear Medicine, StabroekNews reported.

“This was my way of giving back to Barbados in a form of philanthropy, by assisting the QEH in its continued modernization program," it quoted Rihanna as saying. "I believe that this will have a huge impact on the people of Barbados; this was all done to save lives or at least extend it. … I’m really excited about it.”

Clearly, Rihanna has put the cash she made selling her "Diamonds" to good use: Billboard.com reported the first single from her new album, "Unapologetic," hit No. 1 on its Hot 100 list last month.
