Miley Cyrus Talks Being Face of MAC Viva Glam, Gets Honest About Grammy Nomination

— -- Miley Cyrus is fresh off her worldwide “Bangerz” tour but she’s not slowing down.

She’s joining the ranks of Rihanna, Lady Gaga and Nicki Minaj as the new face of MAC cosmetic’s Viva Glam campaign.

The 22-year-old talked with “Good Morning America”’s Cameron Mathison about the campaign.

All of the proceeds from sales of Cyrus’ custom lipstick will go to the MAC AIDS Fund, which supports people affected by HIV and AIDS.

Cyrus wants to empower those affected by the disease as well as inspire hope for a cure and an end to stereotypes about people with HIV and AIDS.

“It's fun for young people to get to buy a lipstick and know that it's going to actually go to changing the way that their future is going to be,” she said.

On a recent visit to the Los Angeles LGBT Center in Los Angeles, the “Wrecking Ball” singer talked with young adults there. She appeared very passionate about the project.

Asked whether she considered herself a role model for the youth at the center, she replied: “I can actually say I am for what I know of what is important to teach people -- and what is important to teach people is that … you can't judge other people.”

It’s important to Cyrus to use her celebrity to help others.

“I realized that if there's going to be all this attention on me all the time, no matter what I say, no matter what I do, I should be saying something and speaking on behalf of those that kind of feel like they have no voice,” she said.

Mathison also asked her what a stranger would be surprised to learn about her.

She replied: “I'm not the way that people try to make me seem … I don't go around just trashing hotel rooms and partying, that I'm actually working on, you know, music that I love and being involved in things that I love.”

Cyrus is nominated for a Grammy Award in the best pop vocal album category for “Bangerz,” and while she’s excited to attend the Feb. 8 event, she isn’t holding out much hope.

“I'll probably never get it, but I'm stoked about the nomination,” she said.
