NEW SONG.. MY PERFECT BITCH..

KANYE WEST TO 
Kim Kardashian's 

Must be true love ... Kanye West just announced his new song "Perfect Bitch" is about his girlfriend Kim Kardashian.


The song has NOT been officially released yet -- but a source told the Daily News, the lyrics are "about his search for the perfect woman and how he has now found the 'perfect bitch.'"

Rap's got a terrible reputation of being misogynistic -- and using the word "bitch" doesn't help -- but this song seems to have a romantic spin on it ...
