50 Cent slams Kim Kardashian, calls Kanye's girlfriend 'trash'

50 Cent has never been a fan of rival rapper Kanye West -- and he doesn't think much of his girlfriend, Kim Kardashian, either.

In an interview with hip-hop mag XXL, Fiddy is asked about the inspiration for Kanye's song "Perfect B****."

"If that man feel like she perfect, then she's perfect," he begins diplomatically.

"He could mean it and you'll end up singing the words to it because he's Kanye," continues the "In da Club" singer, before delivering a final biting blow.

"You know how it is? One man's trash is another man's treasure."

Ouch.
