Rihanna drinking beer as she attends grandmother’s funeral

As Rihanna prepared to attend her grandmother Dolly’s funeral today in Barbados she tweeted a picture of herself, make-up free and holding what appears to be a beer in her hand.

With heavy bags under her eyes, Rihanna, 24, looked absolutely exhausted in the snap.

The singer seemed to be standing in her hotel bedroom and was wearing a simple white vest.

She captioned the photograph: “I had to!!! Sorry granny”, clearly referring to Dolly.

Today Rihanna was seen making her way to her grandmother’s funeral in Barbados.

Emerging from as chauffeured car, she was wearing all black – the colour of morning.

With her head down and hair covering her made-up face, the pop star looked devastated.

Rihanna has been through a tough few days, and there were fears that the very recent death of her grandmother would cause her to pull out of her headlining gig at the Wireless Festival over the weekend.

But the singer managed to plaster a smile on her face and dazzle the crowds at the Hyde Park event, after flying in shortly after attending Dolly’s first funeral in New York.

Rihanna closed her second festival in as many weeks, and didn’t disappoint the waiting fans.
