New pictures of ravishing Rihanna wearing nothing but a black bra and a fur coat in a ski chalet setting sent fans' pulses racing over the weekend (08-09Dec12).

The latest saucy shots come courtesy of what seems to be a winter break with model pal Melissa Forde, who also appears in the photos. Rihanna poses by a roaring fire, sipping wine and smoking.

It's not the first time the sultry Umbrella singer has posted provocative pictures online, but she has never before gone without bottoms for her Twitter shots.

It could all just be a reminder to on/off boyfriend Chris Brown what he could be giving up if he starts messing around again.

Prior to her wintry bottoms-off photo exhibition, Rihanna appeared to launch a tirade against Brown following reports suggesting he had been spotted with his ex Karrueche Tran - the girl he dumped to re-romance Rihanna.

On Friday night (07Dec12), the furious We Found Love singer fumed, "Examine what you tolerate, goodbye muthaf**ker," adding, "You give, you get, then you give it the f**k back".

It's not clear if Brown was the object of her ire, but if he was the drama was all over within hours - Rihanna posted another tweet on Saturday, writing, "Miss you," accompanied by a shot of her cuddling her boo.
