In a salute to the women who aren't afraid to take

their tops off for their adoring public - whether they

know their adoring public is looking or not -

here are some celebrity nipple sightings

When famous boobs call, who can't help but listen?

Apparently, people who know about these things claim that topless sunbathing is going out of fashion in France. But please don't tell the celebrities that.

Women of the world, are you tired of keeping your top on? Last Saturday, you could have fought for your right to go topless as part of National Go Topless Protest Day.

Sure, the movement may have been founded by some crazy UFO religion, but that shouldn't dampen your enthusiasm for baring it all.
