Like Nicki Minaj and Lady Gaga before her, Rihanna, who turns 25 today (Feb. 20) is partnering with edgy cosmetics giant MAC for four collections.

RiRi said that teaming up with MAC is a "no brainer" (quotes via The Telegraph), since the pop diva and the cosmetics company have a similar aesthetic. Plus, Ri loves their red lipstick. Mwah!

"When you think of makeup, the brand that pops into your mind -- for something legit -- is MAC," Rihanna, a former CoverGirl spokesperson, said. "Whatever color you want, it's like 'Let's go to MAC.' I've been using MAC on tour for such a long time it was a natural fit for me. I have always loved makeup, and I always said that if I do it, I want to do it with a credible brand."

One of her first products in the partnership is her take on MAC's best-selling Ruby Woo red lipstick. It'll be called RiRi Woo and is her interpretation of scarlet.

There will be four collections dubbed RiRi (Hearts) MAC. The first will land on counters in May, when her Diamonds tour is in full effect. A pop-up shop will preview the products on the tour.

The singer was also involved in the creative process, saying, "There's so much to choose from, and you can mix different textures with different colors and different greens in different eye shadows. I learned so much about the detail of make-up and what makes things look different. What makes it apply different is really important. Every little detail is important."

Rumor has it she didn't do much more than give her opinion and suggestions on her River Island fashion collection, which looked ripped straight from her closet. But it sounds like she really got her hands dirty – with cosmetic pigments and ingredients -- with MAC.
