Watch out, people... slowly but surely, Rihanna is taking over the world.

At just 24 years old, the singer has won multiple Grammy Awards, appeared on the big screen, and launched several fragrances. So, what's next? Her very own makeup collection, of course!

The singer has just signed a deal with MAC Cosmetics to create her own line of makeup. "I've been using MAC for such a long time on tour it was a natural fit for me," she tells WWD. "I have always loved makeup, and I have always said that if I do it, I want to do it with a credible brand."

Rihanna's first venture into makeup is a red lipstick called RiRi Woo, which will release in early May during her tour stops at Brooklyn's Barclays Center. All together, she will release four collections called RiRI Hearts MAC, which will release throughout 2013. RiRi Woo will be the signature product, featured in all four collections.

The company stresses that this deal isn't just Rihanna slapping her name on MAC makeup, but a true collaboration on both ends. Also important to note is that Rihanna's personal life choices (like her highly criticized reconciliation with Chris Brown), doesn't seem to be getting in the way of the deal.

"She's a grown woman and whatever makes her happy makes us happy," says John Demsey, president of MAC's parent company Estee Lauder. "Life's complicated. Far be it from us to judge."
