"Hugs not drugs," "Mow your grass, don't smoke it." The latest Hollywood adage seems to be: "Take your clothes off if you believe in this cause." During the past few years, more and more celebs have been taking it all off for organizations supporting everything from protecting our furry friends to our own health.

Although we don't mind seeing our favorite celebs go au natural (like Khloe Kardashian, Adam Levine and Bethenny Frankel above), it seems like a few of these birthday suit celebs overexposed themselves just for the sake of some much needed publicity. Hey, it's easier than feigning outrage over a leaked video of a romp in the hay.
