M.A.C taps Australian singer for Viva Glam campaign

A model that refuses to show her face to the camera may seem an odd choice to front a cosmetics campaign, but when that model is Sia, it's an understandable exception to the case. 

The Aussie singer has just been named the latest superstar to front M.A.C's Viva Glam lipstick campaign – Viva Glam being the brand's long-running charitable initiative that supports those affected by HIV/AIDS. Previously the campaign has been fronted by the likes of  Taraji P. Henson, Ariana Grande – and pre–Fenty Beauty – Rihanna.

Sia famously covers her face during media appearances and on stage performances to allow her to live a life without the public recognition most celebrities get. But for M.A.C she has revealed a sliver of her face with Viva Glam's new red lipstick on full display.
