Kanye West to Kim Kardashian: Slim Down!

Kanye West has a message for Kim Kardashian: be more like Beyonce!

Sources tell OK! Magazine that the rapper is urging his curvy girlfriend to follow the same routine as pal Jay-Z's wife, who shares a similar shape, when she slimmed down for Dreamgirls.

"She proved you can get that supermodel body using her lemon juice, cayenne pepper and maple
syrup diet," an insider says of how Beyonce lost weight for a role in that musical.

West reportedly has no problem personally with how Kim looks - at least one Kanye West sex tape does feature a Kim Kardashian lookalike, after all - but...

... "he wants her to be the face of his clothing line," this insider adds. "To do that she has to fit into the clothes."

Will Kardashian abide by her man's request? We'll see. She typically only loses weight when paid to endorse illegitimate dietary supplements.
