The 24-year-old singer was pictured in just a bra and fur hat in two snaps taken by her pal Melissa Forde, the setting for which appears to be an alpine-style hotel room.
And RiRi has been tweeting a string of messages - including "examine what you tolerate", "goodbye muthaf**ker" and "you give, you get, then you give it the f**k back".
Forde also posted a pic of a handwritten note which read: "The worst thing about being lied to is knowing you weren't worth the truth! Being with no-one is better than being with the wrong one."
The intriguing messages follow an alleged falling out between RiRi and back-on-again boyfriend Chris Brown - with reports that he was partying with an ex-GF on Friday night.
But things appeared to be back on track between the couple later when RiRi posted a pic of herself being held by a tattooed arm - with the caption: "Damn...... I miss my ni**a."
We told you last week how RiRi had got a new tattoo in tribute to Breezy.
