Chris Brown Adds Shirt Featuring Rihanna To His Black Pyramid Clothing Line [PHOTO]

In the black-and-white photo, Rihanna is wearing a military-print comforter over a bra and underwear, as Brown sits in the foreground, smoking.

Brown posted the picture to his Instagram account, along with the caption “Black Pyramid Tshirt!”

Brown launched the fashion line alongside Pink + Dolphin founders Neima Khaila and Cena Barhaghi in November. At the Black Pyramid launching event, Brown explained the name, saying, “We really haven’t mastered the art of making a pyramid ourselves, like the ancient ones.

"The black pyramid label is basically an unknown art. So I think my painting, my designs, whatever I do fashion wise is unknown to a lot of people.”

But Brown is not the only one with a clothing line.

Rihanna also tweeted earlier this week about her own Spring/Summer 2013 collection with River Island that will reflect her personal style.

“My [expletive] so Bvalgari … Just directed my first ad campaign for my new collection with River Island, Spring/Summer 2013!! And that’s a wrap at the end of a 2 day shoot w/ MARIO SORRENTI,” Rihanna tweeted.

In July, Rihanna expressed her enthusiasm concerning a fashion line, saying in a statement: "I've been wanting to design my own collection for some time. River Island is the perfect partner for me to collaborate with and working with a British, family-run business also really appealed to me."I find London really inspiring and River Island loves to have fun with clothes. I'm looking forward to working with them and creating something really special."River Island said: "We're so pleased to announce an exciting collaboration with Rihanna. Yep, she will be designing her first clothing range exclusively for River Island."We're all huge fans of Rihanna's style here at River Island so you can imagine how flattered we were when she approached us about working together and bringing our fashion experience to her range."
