Nicki Minaj’s Pink Friday lipstick for MAC Cosmetics has become a best-seller, according to the rapper’s latest tweet.

The lipstick shade – a ‘Barbie pink’ – has helped to raise the most money than any other color for the MAC Aids Fund, as part of the brand’s Viva Glam collection.

The fact that Minaj often wears the color while judging American Idol has probably led to teens and Idol fans seeking it out in stores.
