Rihanna has been hanging out in COCO CHANEL's apartment.

The singer visited the late legendary fashion icon's Parisian home (04.06.13), fuelling speculation the Bajan beauty has landed a secret ad campaign deal with the high end brand.

The 25-year-old star first made a trip to one of Chanel's flagship stores, and was allowed to pick any accessory she wanted.

She showed off a snapshot her favourite piece, a yellow Lego box clutch, writing on Twitter: ''Thank you to my dear friends at Chanel Paris!!!''

Rihanna was then given the once-in-a-lifetime privilege of being lent the keys to fashion label founder Coco's flat on the ultra posh 31 Rue Cambon, above the Chanel Boutique.

The 'Stay' hitmaker gleefully tweeted: ''Got the keys to #CoCoChanels apartment!!! Yesterday=Most Legendary day in Paris!!!! (sic)''

Once let loose inside, she busied herself posing in iconic locations around the glitzy apartment, made famous by Coco's personal photographs.

Completely decked out in the label, wearing white sunglasses, their trademark bling and a jacket and skirt combo, Rihanna even replicated an old picture of the late fashion pioneer, lounging on a chaise with a cigarette in her hand.

The original picture of Coco was visible in her lap, and Rihanna captioned her copycat snapshot: ''Replicating a #Coco moment''.

She then pretended to have a clothes fitting in the same spot Coco used to do hers, joking on the social networking site: ''Checking my designs where #Coco checked hers!!! #imjustdifferent (sic)''

The pop superstar concluded her fabulous fashion-filled day in style, having dinner with designer Azzedine Alaia, who is famed for his sexy ladieswear.

She posted a picture of him, adding: ''Mr Alaia getting all blushy after I planted my lipstick on em!''

Rihanna was rumoured to be collaborating with the fashion house - of which Karl Lagerfeld is the creative director - in February, but Chanel denied the claims in April.
