She's not so bad, been ok in a couple of films - if she sticks to her strong poiints (posh, English) she can handle it, but pretty dire if she tries anything else. As role models go I'd put her a long way above Paris, she's not incredibally stupid, doesn't go aorund shagging anything that moves and actually does at least a little work for her cash. As to her attractiveness, well I'd say she's possessed of classic beauty (whatever that is), but could do with a fair bit more weight - for her own sake as much as anything.
Not that I actually give a shit mind you.
