Cheyenne Tozzi is a model from Australia. We have given her the nickname Koala Bear because Koalas come from her native country, and because Cheyenne Tozzi is reportedly hooking up with the greatest ursine specimen in the celebrity gossip world, Brandon "Greasy Bear" Davis. We hope to see more Cheyenne Tozzi in the future. This is true whether she's with Brandon Davis or not. She's hot.
