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'.
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'. Pls get a life girl as in double **dahhhhh..lol
