Black and white photoshoots clearly are one of Rihanna‘s favorite things. Having recently re-entered the dating market, Ri-Ri’s got a lot of other things on her plate as well.

The Barbados native graces the cover of the newest issue of W magazine and does so in style. In fact, she’s so fashion-conscious that she’s hired bikini designer Celeste Johnny to design a custom bikini line for her. She recently sported a suit by the designer on her romantic getaway with new flame, Matt Kemp.

But it’s not all skimpy swimwear and fashion magazines with Rihanna. She’s currently hard at work to help 26-year-old Nigerian sledder Seun Adebiyi, who is currently battling Leukemia.

She tells press, “Leukemia interrupted Seun’s dream of being the first Nigerian in the Winter Olympics, but together we can help him make his dream come true. We need to find him a bone marrow donor!” She seems to be doing all she can to help Leukemia patients get the bone marrow they need–and doing so in style.
