Lady Gaga in the company's Viva Glam 2011

The MAC Cosmetics has signed with Lady GaGa in the second year running as spokesperson for the Viva Glam campaign. GaGa joined Cyndi Lauper for the 2010 campaign that was launched earlier this year.

The company said the campaign GaGa-Lauper was the biggest success of the MAC AIDS Fund, raised more than $ 190 million for the cause, since its founding in 1994.
For the solo campaign in 2011, GaGa was photographed by Nick Knight and dressed by Nicola Formichetti. Check out the first photo essay:
