Kanye West wants Kim Kardashian to lose weight

The 'Mercy' rapper is said to have urged the 31-year-old reality TV star, who is famous for her curvy figure, to slim down, reported Contactmusic.

"He even suggested Kim drop 20 pounds, arguing that Beyonce has a similar shape and she proved you can get that supermodel body using her lemon juice, cayenne pepper and maple syrup diet.

"He says he wants her to be the face of his clothing line... But to do that she has to fit into the clothes. It's really uncomfortable - her shape is what made her name. He has a long-term fantasy of turning them into the new Beyonce and Jay-Z power couple, but getting Kim to starve isn't the way to do it," a source said.

West, 35, had recently asked Kardashian to ditch her trashy style and start taking fashion tips from Britain's Duchess Kate Middleton.
