Ariana Grande is the new 2016 Viva Glam spokesperson for MAC Cosmetics.

The pop star announced the news herself on the live video streaming service Periscope, where she provided a preview of the new colors: a dark plum lipstick “to represent the bad girl in you,” and a light pink lipgloss “to represent the good girl in you.”

Take a look at the tweet by MAC Cosmetics:

All proceeds of the sale will go towards the MAC AIDS fund.

The products will be released in January 2016.
