Kim Kardashian has always been a superstar in Kanye West's eyes -- figuratively and literally speaking. According to new media reports, the "Mercy" singer has long had the 31-year-old reality star on his mind during his sexual exploits, even before they were an item. New reports indicate Kardashian has been the other woman in West's life for some time. Sources tell TMZ that prior to shacking up with the buxom brunette, West frequently called upon her earliest body of work to help him get going. Insiders say that West would bust out her homemade sex tape, Kim Kardashian: Superstar, to put him in the mood. It's no secret that the controversial rapper wanted to make Kardashian his leading lady for years. TMZ maintains that West tried to get her to sack ex-boyfriend and NFL player Reggie Bush almost three years ago. Now, West's wildest dreams are finally a reality. The sex tape, which did gangbusters through porn empire Vivid Entertainment, isn't going anywhere anytime soon, especially since West recently memorialized it in a single on his upcoming album. In the new single "Clique," West raps, "Eat breakfast at Gucci. My girl a superstar all from a home movie."
