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.

And rarely getting time to see her maternal grandparents Clara and Lionel, Rihanna looked thrilled to be with them, uploading a series of photos of them cuddling up on her Twitter page.

After buying some food for the party in Whole Foods, Rihanna helped out at the bash by frying up some food for the Bajan-style meal.

She admitted her grandfather was confused by her ever-changing hair colour, which is currently a mix of blonde and black, and still calls her by her Christian name Robyn.

She wrote: '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 (rolling on the the floor laughing). No words.'

Rihanna also tried to get her grandmother trending on Twitter with the hashtag #grangrandollybday.

As well as photos of her cuddling her grandparents, Rihanna also uploaded images of Clara eating her birthday cake and kissing her husband.

Clara and Lionel originally met in Guyana, where they married before moving to Barbados, where Rihanna famously grew up.

However, they moved to Brooklyn, New York several decades ago, with Rihanna as regular visitor when she was growing up.

Rihanna used to stay in her grandparents' apartment near Flatbush Avenue during the summer holidays as a child.
