Nicki Minaj and Ricki Martin for MAC

Nicki Minaj and Ricky Martin teamed up for MAC. They are the faces for 2012 MAC AIDS Fund Campaign.

The purpose for this campaign is to raise more awareness for about the problems of the world and the power that lies within us to solve them.

One of the subjectes the two stars talked about at the show they put on the Stage 37 was marriage, carrer and Whitney Houston.

"I felt like Whitney was part of my family, of everyone's family," said Minaj cited by WWD. Ricky Martin also said that "She did so much, and her music will make her live forever - she will never truly die." 

The MAC AIDS Fund campaign gathered about 700 people including Macy's executive Terry J. Lundgren and fashion icons like Alexander Wang.
