MAC surprises us once again with its newest collaboration. The famous brand is going to release a new Viva Glam lipstick on January 2018. This time, Sia is the ambassador of the campaign, following stars like Lady Gaga, Nicki Minaj, Rihanna, Miley Cyrus, Ariana Grande, and most recently Taraji P. Henson and Jussie Smollett. The well-known singer always tries to hide her identity, especially her face, so it came as no surprise that she poses in that way that the focal point is her red lips. The lipstick is a warm, vivid, statement red with a velvety matte finish. The artist’s name appears on the matte black packaging, written in vibrant red.
