Kim Kardashian is keen to bare all for Playboy again after becoming a mum to baby daughter North this summer (13), just so she can show those who poked fun at her pregnancy weight gain she's hot again. The reality TV star, who became engaged to boyfriend Kanye West on her 33rd birthday last week (21Oct13), stripped for the December 2007 issue of the men's magazine and she's keen to appear naked in Hugh Hefner's publication again after losing her baby weight. In a candid chat with sister Khloe, which aired on the family's Keeping up With the Kardashians in America on Sunday night (27Oct13), she confessed, "I just wanna come out to the world, like, naked and be, like, 'I look so hot. I'm back! You all called me a whale, Shamu, a cow...'" And she revealed there's one special part of her body she'd like the world to see: "When I came back from the hospital, the first thing I did was go and look at my vag (vagina) in the mirror and it looks better looking than before."
