Listen to Rihanna on iHeartRadio

Rihanna has inked a deal with MAC Cosmetics.  On Wednesday, which also happened to be her 25th brithday, she announced on Twitter that she'll be launching a series of collections with the beauty company. 

She tells Women's Wear Daily that teaming up with MAC was a "no-brainer" and that she's excited to work with the brand that's been her personal go-to for years. 

The first product set to come out will be a red lipstick called "RiRi Woo."  It will become available at a pop-up shop on May 4th, when Rihanna brings her tour to Brooklyn's Barclays Center. 

A summer, fall and holiday collection will follow "RiRi Woo" through the rest of 2013.  The holiday collection will be the most extensive, including a line of makeup bags, nail polishes and more. 

The partnership is a big step for MAC.  It's the first time the company has inked a multi-collection deal with a celebrity outside of its "Viva Glam" project.
