PHOTOS: Rihanna turns up the heat, tweets seductive semi-nude photos

She recently bared all for the cover of her seventh studio album Unapologetic and again when she fronted GQ magazine.

But keen to show her figure off some more, Rihanna has stripped off again in a series of saucy Twitter pictures.

Photographed by her best friend Melissa Forde, the 24-year-old Diamonds singer just about manages to retain her modesty as she strikes a pose.

 

In the first picture, which Forde uploaded to the micro-blogging site via her Instagram account, a bare bottomed Rihanna eyes the camera lens as she kneels.

Holding her glass of wine in her hand with a cigarette in her mouth as she pouts, Rihanna shows off her bed eyes and part of her freshly cropped black hair.

With a coating of scarlet lipstick completing her look, the caption on the image reads: ‘Sneak peak new photoshoot @rihanna #MTFphotography’.

Enjoying a quiet drink: Rihanna took a sip of wine from her glass as she turned away from the camera

 

In the second snap, Rihanna raises the temperature as she looks away from the camera while taking a sip of wine from her cup.

Wearing just a black lace bra with a fur hooded coat over her head, the Barbados born star stretches her feet out onto a fur rug.

Showing off one of her 18 tattoos, Rihanna rests her back against a fire place as she holds a cigarette in her other hand.

Getting more creative with her descriptions, with the second image Melissa tweeted: ‘Who needs fashion when there’s p**** @rihanna #MTFphotography’.
