Kim Kardashian is determined to get skinny again, or perhaps the better word would be "attractive", since she was never skinny to begin with.  She wants to pose nude once more. Via Contact Music:
Kim Kardashian wants to pose naked for Playboy. The reality TV star has expressed her desire to do a "nude shoot" for the men's magazine after she gave birth to her daughter North West - her first child with partner Kanye West - on June 15. She made the revelation in scenes filmed for the upcoming series of 'Keeping Up with the Kardashians' - and has admitted she would like to take part in another risque photo shoot.

Speaking before her baby's birth, she said: "As soon as I pop this thing out, I want to do Playboy or some nude shoot."
Fitting move for a porn star?
