L.A.’s famed Robertson Boulevard got just a little more glamorous yesterday, as M.A.C.’s Viva Glam spokesperson, Fergie, turned up at the flagship store to unveil a much-anticipated new shade, Viva Glam VI. And it was all for a good cause. Just like past Viva Glam shades, 100% of proceeds of the full selling price goes directly to AIDS charities. PEOPLE.com chatted with the singer who dished about her part in developing the new hue. “They brought about 10 different shades and laid them out and let me pick,” she said of the light, shimmer color. “It was important for me to find a shade that looked good on all skin tones — day and night,” she said. “And I love pink!” The singer also stopped by Project Angel Food, a Viva Glam beneficiary, which provides free meals for those living with HIV/AIDS. “This is something that I like doing because it’s not just about me,” she said of the charity aspect of her ambassadorship. “It’s about people and I get to meet their families and hear their true stories. It’s for real and these people are really doing the charity work and putting care into what they’re doing,” she says. You can help support the cause — and look gorgeous doing it — when you purchase the new Viva Glam VI shade at maccosmetics.com starting March 19 or one of the other dazzling hues now.
