She's a diamond in the sky with a heart of gold.

According to E! News, Rihanna donated $1.75 million to a Barbados hospital in memory of her grandmother, who died back in June. 

The 24-year-old singer visited the hospital on Saturday. Thanks to Rihanna's donation, the radiotherapy department at Queen Elizabeth Hospital in Bridgetown was renamed the Clara Braithwaite Centre for Oncology and Nuclear Medicine, in honor of her Gran Gran's name.

For all the crazy stuff celebs do, this was a beautiful gesture and a good use of some of that $53 million Rihanna made this year.
