Thanks to the news that reality star, Kim Kardashian is pregnant, her infamous sex tape is back on sale and selling very quickly too.

Since her and hip hop boyfriend Kanye West announced they are expecting a baby, the x rated video Kim and R&B singer Ray J in 2007 is on high demand and sales are up by 80 per cent.

Vivid Entertainment, which owns ‘Kim. K. Superstar — the video’ confirmed it’s the biggest increase in sales since Kim’s wedding to Kris Humphries.

Reports claim that the sales of Kim’s sex tape — across video-on-demand, online, or DVD — have steadily increased every month since Kim and Kanye started dating last spring.

Kim sued distributors Vivid Entertainment for ownership of the 2003 tape — allegedly stolen during a house move — but dropped the suit in April 2007 and settled with the company for £3million.
