PETA's new campaign Fur-Free & Fabulous features Lady Gaga, Pink and Mariah Carey, and not because of their amazing voices, but because they have always been against the wear of fur. And the fact that Lady Gaga wore a meat dress at 2010 MTV Video Music Awards doesn't count...

Here's what PETA says of the three singers

"These musical powerhouses have good reason to shun fur—every fur coat, vest, hat, or fur-trimmed accessory causes animals an immeasurable amount of suffering and ends their life. Foxes, minks, rabbits—even dogs and cats—are bludgeoned, stomped, electrocuted, and gassed to death, and many are skinned while still alive. You can help put an end to this unimaginable cruelty by choosing never to buy or wear fur or fur-trim."

The ad will be released two weeks before the Grammy Awards and for the ones who lives in L.A., the billboard will be located at the intersection of La Brea and Sunset Boulevard.
