Miley Cyrus just went to work promoting MAC Cosmetics‘ two new Viva Glam products for 2015, a hot pink lipstick and matching lip glass. Proceeds from the special edition products will benefit the MAC AIDS Fund.

Cyrus was in West Hollywood at an event promoting the new products and campaign. She told Vanity Fair during an interview about the experience of collaborating with MAC on the creative aspects of the campaign, and said:  “I wanted the lipstick to be like hot-pink lava with crushed-up 1,000 disco balls inside. I wanted the set (of the ad campaign) to feel like the lipstick—like I was inside of the tube. That’s what we wanted it to feel like.”

The folks at MAC gave Miley a giant-sized pie of pizza at the event, as you can see in the photo above.

Here’s a few phoos of the new campaign, starring Cyrus.
