I liked Christina before she went all skank on me. She was never beautiful, but she was kinda pretty and really talented. And when she first started out she was petite everywhere, including her chest. Then she decided she wanted to be a dirty nasty ho with fake tits, gross make-up with porn star eyebrows, and absolutely no fashion sense. YUCK!
Jessica is really pretty and mostly natural, and while she is overrated I'd still have to go with her.
