The singer's grandmother passed away over the weekend


Rihanna has taken to Twitter to explain why she wasn’t herself at a gig in Sweden on Saturday night.

Ri-Ri came under fire for giving a ‘disgusting and shameful’ performance on the day her grandmother Dolly passed away from cancer.

Fans were angry with the 24-year-old for arriving 45 minutes late to a gig in Borlange on 30 June and accused her of looking ‘under the influence’ and miming.

‘Goodbye #grangranDOLLY get your beauty rest until I see you,’ Tweets Rihanna, along with a series of photos of Dolly.

The singer recently delayed a trip to the UK by a week in order to spend time with her gran, who was being treated in a New York hospital.

Fans were quick to take to Twitter to console the Bajan star after she revealed the news and she later received a message from her ex-boyfriend Chris Brown‘s mother Joyce Hawkins.

‘Angel may God be with you and your family in your time of sorrow. Love you angel,’ Tweeted Joyce.
