Naked Ambition: 15 Bare-It-All Music Videos

 It's no secret that pop stars like to bare their bodies, whether it's on stage, on the red carpet, or in a music video. Big names like Katy Perry, Lady Gaga and Gotye left little to the imagination in their video hits, and just this year, we saw nudity (and controversy) pop up in videos from the Flaming Lips and Sigur Ros. Check out our list of 15 videos that aren't afraid to show some skin.

NSFW: Sigur Rós (w/ Shia LeBeouf), "Fjögur Píanó" (2012)

Shia LeBeouf literally bares it all in the avant-garde short film for Sigur Rós' "Fjögur Píanó," which is definitely NSFW. The clip chronicles the ups and downs of a very sad-looking LaBeouf and his graceful girlfriend -- or at least that's what it seems to be chronicling. The incredibly strange video is difficult to decipher, but it keeps viewers watching for an astounding nine minutes.

Katy Perry, "California Gurls" (2010)

Katy Perry strips down before slipping into her cotton candy cloud-covered bed in her video for "California Gurls," which takes place in the sweet land of "Candyfornia." Sugar and spice and everything nice, that's what Katy Perry and her gurls are made of.

Gotye, "Somebody That I Used To Know" (2011)

Gotye bared more than his soul in the video for his chart-topping single -- the Aussie singer shows off every inch of his body as he's painted with colorful shapes, standing still and crooning "now you're just somebody that I used to know." Featured songstress Kimbra goes just as buff as she's stripped of her geometric paint in the viral video. 

Blink-182, "What's My Age Again" (2000)

Pop-punk pranksters Blink-182 forget their gym shorts and take a leisurely, naked jog through the streets, encountering a memorable cast of characters along the way. The boys were actually wearing thongs during most the outdoor scenes, but they let the cameras capture it all in the studio shots.

Britney Spears, "Womanizer" (2008)

Britney got her sauna on during the filming of her 2008 comeback clip, which allowed her to show off her re-buffed bod. The song quickly became Brit Brit's first No. 1 hit in nine years. Coincidence?
