She had attended her grandmother's birthday party earlier in the day in an outfit appropriate for a family gathering. But after being playing the perfect grandchild Rihanna slipped back into her sexed-up style donning a pair of leather trousers and a partially see-through top for a night on the town. The singer had opted to go without a bra meaning that flashes of her flesh could be seen through the mesh material as she headed to a nightclub in New York last night. Rihanna finished off her look with bright red lips, a pair of Wayfarers sunglasses, and a jacket with a fur lined collar. And the singer, real name Robyn, was showing off her most recent hairstyle, a wig that boasts dark roots and bleached blondes tresses. Earlier in the evening Rihanna had spent time with her family celebrating her grandmother Clara 'Dolly' Brathwaite's birthday with an intimate gathering. And it appears that Rihanna isn't the only cool one in her family - which she demonstrated by sharing a series of snaps from the event. In candid photos from the party, Dolly was seen wearing baseball caps, sunglasses and chains over her quilted dressing gown as she struck a pose for her famous granddaughter's camera.
