The singer's performance was panned by the audience of Sweden's Peace & Love music festival who did not know that her grandmother had just passed away.
Rihanna is mourning the death of her grandmother, Clara "Dolly" Brathwaite, who lost her battle with cancer. The Barbadian singer took it to Twitter to express her sadness, writing "Goodbye #grangranDOLLY get your beauty rest until I see you."
Dolly had been hospitalized at the Memorial Sloan-Kettering Hospital in New York. It is unclear when she passed away but Rihanna put up photos of her beloved grandparents on Twitter in the early hours of Sunday, July 1.
The previous night, she just came off a headlining performance at Sweden's Peace & Love music festival. She arrived at the venue 45 minutes late and some people left after she sang the first song due to reportedly shaky performance. It was thought that Rihanna was quietly dealing with the news of her grandmother's death, unbeknown to the audience. She further upset the crowd by mistaking them for Norway.
Her grandparents play a huge role in Rihanna's life as she often spoke about the values of her upbringing. Condolences from fellow celebrities have poured out including the one from her ex-boyfriend Chris Brown. "Praying for family and the lost loved one. She was like my grandmother. Love you GRAN GRAN! RIP," Brown wrote on Twitter.
