Chelsea Handler's Got A Bone To Pick With Kim Kardashian's Butt

The comedian takes issue with Instagram's handling of nude photos.

Instagram has not seen the last of Chelsea Handler's wrath. In a second bid to call out the social media network on its sometimes questionable pick-and-choose methods of nudity moderation, the comedian is taking advantage of Kim Kardashian's explosive Paper magazine cover.

"Can you believe more than 2 ass can fit on the same screen? Guess which one's real. Your move, instagram," Handler wrote with a side-by-side photo of Kim K.'s booty and one of her own.

The former "Chelsea Lately" host then followed up with a reprise of her topless horseback-riding photo, originally intended to parody Russian president Vladimir Putin's own shirtless escapades, comparing her treatment yet again to Kardashian's.

"Just so I'm clear, Instagram...it's ok to use nudity to sexualize yourself on your site, but not to make a joke? I'm just so confused," Handler captioned the photo.

Handler declared several weeks ago that she would boycott the photo-sharing service and continue posting pics exclusively on Twitter.

It appears that Instagram has accepted the comedian's bare-breasted challenged, removing the photo after it remained live for nearly 3 hours. However, the photo featuring Chelsea's rear end remains active.

The social network's community guidelines remain vague with regards to nudity, explaining: "If you wouldn't show the photo or video you are thinking about uploading to a child, or your boss, or your parents, you probably shouldn't share it on Instagram. The same rule applies to your profile photo. Accounts found sharing nudity or mature content will be disabled and your access to Instagram may be discontinued."
