The singer's grandmother passed away last weekend
Rihanna canceled his appearance at Rock in Rio Madrid due to the death of his grandmother.
The singer of "Where Have You Been" is present in the Spanish capital on Thursday (5), but gave up the event because of mourning for the death of Clara "Dolly" Braithwaite, who lost his battle with cancer at the end of weeks.
The festival organizers, who are looking for a replacement, apologized to fans and promised to return the money paid for tickets.
On Sunday (8), Rihanna must participate in the Wireless Festival, held in London.
Recently, Swedish star's fans criticized his performance off the festival Peace & Love. Some of them rated the show as "disgusting and disgraceful", while others said that the singer appeared to be drunk and had forgotten the name of the country where they were.
In recent days, Rihanna has shared family photos with fans via her Twitter page.
