Seems like people are more curious than ever to see Kim Kardashian’s pre-pregnancy body.

TMZ reached out to Vivid Entertainment which owns Kim K. Superstar (a.k.a. the sex tape) and found out that video-on-demand purchases of it have gone up 80% since Sunday.

This is reportedly the biggest sales increase since Kardashian’s wedding to athlete Kris Humphries.

Tape sales overall (VOD, online, DVD) have also increased monthly since Kim and Kanye West began dating last Spring.
