'We Can't Stop' beauty Miley Cyrus will be appearing live on 'Good Morning America' tomorrow morning (January 23) for an exclusive interview. 

The superstar will be promoting her new partnership with MAC cosmetics for its VIVA Glam campaign, which uses proceeds from sales of the make-up to help women, men, and children living with or affected by HIV and AIDS. 

On January 20, the sensation shared a tweet with her 19.1 million followers and explained how the money made from the sales of her cosmetic products will be spent: "Every penny from my @MACcosmetics goes to da @MACAIDSFund to help those affected by AIDS."

Cyrus, meanwhile, recently spoke out about dealing with the paparazzi and confessed that she's sick of being intimidated by photograhers, which is why she needs to stand up against them because so many celebrities sit back and let it happen: "So many people are comfortable ignoring them. I feel like I have to be a voice or no one else will say anything."
