Have you seen Kim Kardashian's ass lately? That thing is massive (yet totally fuckable)! I thought that Jennifer Lopez had the biggest ass in Hollywood, but there came Kim and told J-Lo to move over and make way... there's not enough red carpet in California for two butts that size! Although I think we're better off dealing with Kim Kardashian... at least her butt is natural and she's not a bitch.
On a different note, I personally don't know how they managed to fit Kim Kardashian's ass in her playboy spread. Did they like add extra sheets of paper to the centerfold? I can't remember, and my copy of Playboy from that month has some suspicious white stains so I don't dare touching it ;)
