Kanye West made veiled references to his love for Kim Kardashian in a song recorded as early as 2009, sources extremely close to the rapper tell TMZ. Kardashian was dating NFL star Reggie Bush at the time. In "Knock You Down," the main reference comes in the form of these lines: "You was always the cheerleader of my dreams / To seem to only date the head of football teams / And I was the class clown that always kept you laughing / We were never meant to be, baby we just happened." Later, Kanye says, "You should leave your boyfriend now." Apparently, say the sources, there are more Kanye-Kim references in other songs. Audiophiles, get hunting!
