Rihanna has put a decidedly unique spin on apres-ski wear.

Over the weekend, the "Diamonds" singer, 24, posed for pal Melissa Forde, sipping wine and smoking by a fireplace in a ski chalet-like setting wearing, as usual, next to nothing: A black bra, no panties and a fur coat.

Posting a few of the shots on her Twitter, Forde (who appears to be the photographer) captioned the photos with a quote too X-rated to include here.

Rihanna was slightly less relaxed earlier in the weekend -- launching a tirade against, presumably, on-again, off-again beau Chris Brown.

"Examine what you tolerate, goodbye muthaf****," she tweeted Friday, although she didn't clarify the root of her anger. "You give, you get, then you give it the f*** back" and "Claps for the basic b****."

By Saturday, however, the Grammy winner (who appeared on German TV over the weekend) offered up another shot in which she cuddled with the "Don't Wake Me Up" singer. "Miss you," Rihanna wrote.
