The singer posted a photo of the ad as well as of the lipstick and lip glass on her Instagram, and wrote:
Doesn't she look so hot with that blonde wig and those baby bangs?
MAC Cosmetics also gave a description of the shades:
"@mileycyrus is BACK with a BAM! Our iconic #VIVAGLAM spokesperson has two new surefire hits: a super-sexy bright orange Lipstick and coordinating Lipglass with sparkling pearl shimmer. Get the GLAM online and in stores starting in September 2015."
If you're familiar with the Viva Glam products, then you know that 100% of the proceeds go to the MAC Aids Fund to help men, women, and children living with HIV and AIDS.
It's for an awesome cause AND it's awesome lipstick.
