Gosh, they are both awful! Though I hate the fact Bex's mood changes instantly. Like before the Hanson song was played. One minute she's got a face on her like a smacked ass in the bedroom and the next she's dancing around on the table. That has to be a fake! Get her out! The fact she always has a face on her, annoys me too. That's the thing I hate most in fact

She's meant to be this "uber, happy, stark-raving mad" girl, yet she always looks like she's in a bad mood! False cow

So yes, Rebecca by far
