Wouldn't really call her thick, she has a fat ass but doesn't really have the quads to match it, so I would say that picture is likely photoshop (she's still a beautiful girl but if you know anything about bodybuilding to get a big ass your quads will also grow and that girl doesn't look like she lifts, a nice body but the ass meat don't match the thigh meat).  I've used her before to demonstrate thick but she is a better example of thick white girl
