Just when you thought that Kim Kardashian had a big ole booty. Meet Sara Massey, she holds the world record for the 'Biggest Butt' in the world. Can you believe it's seven feet around, and she couldn't be any happier with her enormous rear end. You would think she would be ashamed about it, but that isn't the case at all. She loves showing off all seven feet of it. Is this what Sir-Mix-a-lot meant by baby got back. LOL!!
