Rihanna has joined the list of elite pop stars and started an exclusive color with MAC. One of the most popular lip colors Ruby Woo, has been "remixed" and renamed Riri Woo! There are said to be slight variations of the color, and the Rihanna fans are going crazy for it! I personally sat on MAC's website for 22 minuted waiting to order due to site overload. Lady Gaga, Nicki Minaj, Ricky Martin (yes Ricky Martin) also have collections with MAC. This is sure to one of the biggest sellers in MAC history! Candy Yum Yum lip color had to be the biggest! Any-woo, the color is available exclusively online while supplies last! Order yours now! Go Riri go!
