Rihanna took soMe time out to cook her grandparents a birthday meal. Rihanna visited her grandparents in honour of Granny Dolly's birthday.

To celebrate her birthday, she went to Whole Foods supermarket and brought a cake for her and some champagne. She then cooked them a meal and later tweeted a photo of the three of them. Rihanna amusingly tweeted that even her grandparents make fun of her hair: 'My GranDad: Robyn how ya is get hair from red to cream to black??? Cuz ya don't carry wigs!!! Ya does wash it out?! Me: ROTFL (no words).' In the photos, Rihanna looked relaxed as her grandparents kissed her on the cheek. The family gathering took place in Brooklyn, New York, where Rihanna regularly visited them when she was growing up in Barbados as a child. The old couple had met in Guyana and moved to Barbados but then decided to settle down in New York.

This is a far cry from earlier this week when Rihanna was spotted meeting friends in New York in a see-through jumper with no bra on, which meant that she had bared her breasts to photographers. She has also recently been seen only in her underwear on a bed as part of a new Armani TV advert.

Rihanna will next be seen starring in the summer blockbuster movie 'Battleship'.
