Get your foam finger at the ready because queen of the twerking Miley Cyrus has been announced as the new face of MAC’s charitable Viva Glam collection, out early 2015.

The 21-year-old singer is following in the footsteps of Rihanna, Lady Gaga and Nicki Minaj to front the campaign. The duo of products in limited edition packaging – an Amplified lipstick and shimmering Lipglass – will come in a bold pink hue (as seen on Cyrus in the campaign imagery).

As usual, all the money from the sales of the products will go to women, men and children living with and affected by Aids and HIV.

Cyrus tweeted about the range saying, 'Going #VIVAGLAM with @MACcosmetics. Look for my lipstick in early 2015.’
