Kanye West has apparently decided to take the old adage "write what you know" to heart.

West opens up about his latest flame Kim Kardashian's XXX past on his latest track "Clique" -- and pretty much admits that the raunchy romp with her former beau Ray J is pretty much responsible for her rise to fame.

On the song -- an upcoming single from the collaborative album "Cruel Summer" -- West raps, "Eat breakfast at Gucci. My girl a superstar all from a home movie."

That second sentence is a pretty clear reference to the 2007 celebrity sex tape "Kim Kardashian, Superstar," which launched Kardashian into the spotlight and toward a reality TV empire.

This isn't the first time that Kardashian has served as West's muse; last month, the rapper 'fessed up that his track "Perfect Bitch" is about her.

"I wrote the song Perfect Bitch about Kim," West admitted in a tweet that has since been removed from his Twitter account.
