Kanye West has urged Kim Kardashian to take style tips from Duchess Catherine.

The rapper believes his girlfriend of six months - who shot to fame after making a sex tape with her then boyfriend Ray J - could learn a lot from the British royal's "poise and sophistication" along with her conservative style.

Speaking about the duchess - who was previously known as Kate Middleton - a source told the Daily Star newspaper, "Kanye has been urging Kim to tone down her make-up and style her hair in a more conservative style, like Kate. And it's not just Kate's regal look that Kanye wants Kim to mimic. He's also told her that she could learn a thing or two about poise and sophistication from Kate."

Kim recently revealed Kanye has managed to convince her to live her life at a slower pace and focus less on her work and more on her personal life.
