It appears Kim Kardashian has a lot more in common with boyfriend Kanye West than just a passion for fashion.  The duo apparently also enjoys filming themselves having sex.

West, according to RadarOnline, has his own sex tape, with a woman who resembles his curvaceous reality star partner.

"The sex tape is being shopped right now and there's a lot of interest, but Kanye is freaking out!" an insider revealed to the celebrity gossip site.

Kardashian shot to fame after a sex-tape was allegedly released by singer Ray-J, her then boyfriend, in 2007 featuring himself and Kim, which certainly increased Kim’s visibility and has since become infamous.

West, in the beginning of his own sex tape, has the woman state that she is a willing participant in the tryst and of legal age. It is evident he knows they are being filmed, as West looks at the camera and turns it off after the sexual escapade.

 "My husband and I don't have sex anymore … that's why I'm here!" the woman in the video says.

A San Fernando sex industry insider told RadarOnline that the video was shot shortly before West started dating Kardashian.

"If this were to hit the market it would be worth a fortune … there would definitely be a lot of people wanting to see this! Kanye was practically in tears when he heard the tape was being shopped,” the insider said.

But apparently, West should be not be too worried if the video is released.

“In my expert opinion Kanye’s performance far outweighs Kim’s!” the insider admitted.

West has yet to comment on the tape, and it remains to be seen how this will impact his relationship with Kim Kardshian.
