Singers Ricky Martin and Nicki Minaj have posed for the MAC Viva Glam line of cosmetics which raise funds for HIV/AIDS research.

The images were shot in Miami on Wednesday by celebrity photographer David LaChapelle, according to a press release.

In February, pop star Lady Gaga introduced her MAC cosmetic lipstick line during an appearance on ABC's morning talk show Good Morning America while dressed as a condom.

“My first experience with my mother that I remember mostly was when she would put her lipstick on in the morning and she would talk to me about life,” Lady Gaga said. “So, I encourage women all over the world – and men, if you fancy lipstick, who knows – to speak with your friends, your parents, your sisters, your brothers, your uncles, your aunts, all the loved ones in your life about safe sex, about protection. Because it [AIDS] is a 100 percent disease that we can protect and that we can prevent, but it is zero percent curable.”

When asked if she sees herself as an activist, Lady Gaga answered that she does.

“I'm most certainly an activist for equality and an activist for youth protection and social justice,” she said. (Watch the full interview on YouTube.)

Other singers who have posed for the label include Elton John, Cyndi Lauper and Boy George.
