TMZ spoke to the folks at Vivid Entertaintment — which owns 'Kim K. Superstar' — and discovered lots of Kim's fans are celebrating the baby with umm … visual aids.

Vivid says video-on-demand purchases of the sex tape have spiked 80% since Sunday night … the fattest increase they've seen since Kim's wedding to Kris Humphries.

Further, Kanye's been boosting biz for months now. We're told overall sales of Kim's sex tape — be it VOD, online, or DVD — have steadily increased every month since he and Kim hooked up last Spring.

It’s pretty much inevitable a “leaked” contraception video is going to pop up in the coming months so enjoy the internet while it’s still standing.
