Kanye West Raps About Kim Kardashian's Sex Tape

Kanye West is finally talking about Kim Kardashian's sex tape ... dropping a line about the infamous XXX video in his upcoming single ... and it's obvious Yeezy is damn proud of his "perfect bitch."

TMZ has obtained Kanye's new single "Clique" from his upcoming album "Cruel Summer" ... and on the track Kanye spits out a lyric to all of the people who have been critical of his new romance with KK:

"Eat breakfast at Gucci. My girl a superstar all from a home movie."

West is obviously referencing "Kim Kardashian: Superstar" ... one of the best-selling sex tapes of all time.

Kim openly credits her initial success to the flick ... and Kanye -- who's a self-described porn connoisseur -- obviously looks at the movie as an X-rated badge of honor.
