The pop star is sharing photos of her shoot with photography duo Mert and Marcus on Twitter.
She describes the theme of the fashion spread as "Eskimo horror," and the cover photo is a close-up of the star covered in heavy tribal jewelry, including a large septum ring.
Another shot has her topless under furs surrounded by two wolves.
RiRi also had the help of two iconic supermodels. She poses alongside both Naomi Campbell and Iman in a separate shoot for "W," celebrating the work of design house Balmain.
The issue, available on newsstands now, has dubbed Rihanna "the world's wildest style icon."
Meantime, she continues her joint "Monster" tour with rapper Eminem, stopping next on Saturday and Sunday at the MetLife Stadium in East Rutherford, New Jersey.
