IT'S GETTING HOT IN HERE: 'KANYE WEST RAPS ABOUT MARRYING KIM KARDASHIAN'...!!!

Kanye West is prepping some new material: his vows.

One month after the Grammy winner professed his love for gal pal Kim Kardashian, 31, on his single "Way Too Cold" (formerly "Theraflu"), he's singing about her again, a source tells Us Weekly.

On an upcoming track by hip-hop artist Pusha T, West, 34, raps, "I saw you in the club in a white dress/Now I want to put you in a white dress."

The lyrics are hardly hot air, says a second source: "Kim and Kanye are 100 percent having conversations about marriage."

Kardashian and the rapper first stepped out as a couple in NYC in March, but an insider close to the duo assures Us their romance was years in the making.

West pursued Kardashian "for a long time" the source explained. Echoed another source, "They've been friends for years. Kim is ready to give it a try now."
