I'm conflicted on the blonde. Obviously the brown hair suits her better, but maybe the blonde is more "her" and she was just fitting into what Joey wanted i.e Aldi version of Kate Middleton. With the return to shooting, the blonde being back and an (online anyway) slightly more relaxed attitude to her food Bradley might not be the worst choice for her. As someone else said further up they're both really into family, fitness, image and money - there isn't much more to them than that.
