Well, here's one for the EWWWW Files: While Kanye West has made it clear he's had a thing for girlfriend Kim Kardashian for a long time, sources say he even used play her infamous sex tape during his liaisons with other women.

According to TMZ, people with "first-hand knowledge of the situation" (what, were they there?) report Yeezy relied on the explicit video to "get him in the mood."

As you'll recall but would probably rather forget, it was 'Kim Kardashian Superstar,' which depicted Kim's sexytime with rapper Ray J, that launched her to fame back in 2003. But although most guys would want to bury that kind of scandalous chapter from a girlfriend's past, West actually brags about it in his new song 'Clique,' rapping, "Eat breakfast at Gucci. My girl a superstar all from a home movie."

He's also said he wrote the song 'Perfect Bitch' about Kim. Aww. (That's a love ballad in their world, you guys.)

This heartfelt and touching display of affection has been brought to you by the letters XXX.
