MAC has just announced Miley Cyrus as the new face of their Viva Glam make-up collection. The Wrecking Ball singer will take on the role of spokesperson for the brand's 2015 campaign, following in the footsteps of Lady Gaga, Rihanna and Nicki Minaj who have previously represented Viva Glam. Miley tweeted about the collection, revealing that her two products, a bright pink lipstick and shimmery gloss will be available to buy in the new year.

  All proceeds made from the Viva Collection go to helping adults and children living with and/or affected by HIV and AIDS. With that in mind, this is one collection we can definitely get on board with.
