So how much are we talking here? This much: Zero. Zip. Zilch. Nada. Yeah, seriously, Kim didn't get a cent for her naked pics.

"Kim was not paid to appear in the magazine," a rep from Paper tells E! News. "She was very excited to work with French photographer Jean-Paul Goude. Paper has never paid anyone to be on its cover."

But then again, there was never a plan to pose completely naked, anyway.

"Kim went into the shoot with just the one cover image in mind: the champagne pic, because Jean-Paul Goude wanted to recreate his pic he took 30 years ago. That was it," a source tells E! News exclusively of the shoot, which took place back in September during Paris Fashion Week Spring 2015.
