Rihanna lent her expertise to a sexy shade of red lipstick for Mac’s newest collection.

The Barbadian beauty joined with the makeup mavens to create the RiRi Woo lipstick grabbing inspiration from the brand’s famed Ruby Woo shade, which happens to be one of Rihanna’s ultimate favorites.

According to cosmetic experts, the shade is flattering on all skin tones and is perfect for a night out or a day at the office.

The super-glam stick of red comes with the “Umbrella” singer’s signature inscription and is available for $16 on Mac shelves starting May 4!
