rihanna & grandmother*Superstar Pop singer Rihanna is human like any other and hurts like any other.

She recently lost her grandmother and is mourning publicly. Clara “Dolly” Braithwaite lost her battle against cancer, says Contact Music.

Rihanna expressed her grief via Twitter after a terrible performance Saturday at the Peace & Love Festival in Sweden.

“Goodbye #grangranDolly get your beauty rest until I see you,” Rihanna tweeted, adding, “#grangranDolly that is all.”

She then followed up with a series of instagram tribute photos.

While in Sweden, she angered fans for taking the stage 45 minutes late and mistakenly dedicated a cover of Bob Marley’s “Redemption Song” to Norway. Some concertgoers walked out, assuming she was drunk.

Rihanna was close to her grandmother, with whom she spent Father’s Day.
