BRIDGETOWN, Barbados (AP) — Rihanna says it’s her way of “giving back to Barbados.” The singer has given $1.75 million to a hospital in her Caribbean homeland.

The donation to buy three pieces of medical equipment was done in memory of her late grandmother. Rihanna was at Queen Elizabeth Hospital in Bridgetown this past weekend for the ceremony to announce the donation.

The hospital’s radiotherapy unit has been renamed the Clara Braithwaite Center for Oncology and Nuclear Medicine after Rihanna’s grandma, who died in June.
