Rihanna is the latest pop diva to collaborate with MAC Cosmetics, something Lady Gaga and Nicki Minaj have done. We predict that one of the most sought after items in the collection will be her interpretation of the brand's iconic red shade Ruby Woo, dubbed "RiRi Woo." You can see it now!

It's a rich and creamy shade of scarlet, while the bullet is stamped with Ri's signature. It's almost too pretty to use. We said "almost."

We're predicting a quick sell out of this lipstick at MAC locations. It looks like it could be flattering on an any and all skin tones, and is classic in its hue.

The singer will be sporting the shade throughout the rest of her Diamonds Tour.

The lippie will retail for $16 and lands on counters on May 4. Be sure and grab a stick or two, since we expect that it's going to go fast.

In other RiRi news, she is not the new face of Chanel, as was previously rumored. She has been photographed wearing a the brand's iconic interlocked C logos lately. But the design house shot down all the chatter that Ri was its new spokesmodel. Coco's progeny ain't talking that talk, yo!
