Lisa Marie, Eve and Dita Von Teese are the latest ladies to join the MAC Viva Glam campaign. The girls are promoting an awesome product and better yet, 100% of the sales from the latest Viva Glam lipsticks and glosses will be donated to HIV and AIDS programs. No wonder celebs want to get involved in this one. Here's why Lisa Marie said yes:

Presley said she agreed to participate in the campaign because of its fundraising efforts.

"MAC is actually, honestly, really true blue about its charity," the 38-year-old singer — and daughter of Elvis Presley — told The Associated Press in a recent phone interview.

"You can see it making headway. They've raised $70 million that's been used incredibly well. It's not a campaign full of fluff, and I'm not a fluff person."

The ladies look a little stiff in the press shots but they loosened up as the event went on. Many celebs attended the Viva Glam dinner and press conference to celebrate the newest launch. Lots and lots of pics including Ms. Aguilera, Drea de Matteo, Emmy Rossum and Kristin Cavallari so
