Her see-thru underwear!
Now, I've got nothing against see-thru panties (I'm enough of a gentleman not to detail the incident that won me over to that opinion), but there has got to be some sort of manual or instructional-device given to all young celeb-utantes that opaque panties are required when wearing a dress out in public or else you'll be considered a skank (ie. Paris, Britney, Lindsay, etc.). The agent who said "any publicity is good publicity" was definately lacking in moral character.
Look, I don't mean to call her a skank, but I had hopes that Emma wouldn't be one of those girls. Of course I also thought that Jamie-Lynn Spears would redeem her family-name (she had her own television show on Nickelodeon for Pete & Pete's sake!), but she had to go and get knocked-up! While Miley Cyrus is still only 15, there is some evidence that the Hannah Montana star is on a slippery-slope to skank-ville (although the jury is still out on that matter). Heck, I once thought that Ashlee Simpson was the saner of the Simpson girls. Boy, was I wrong!
On the bright side, there's our girl Hayden Panettiere. Cute-as-a-button Hayden has been seen in public with Miss Hilton, however any compromising pictures have been relatively tame (ie. her panties weren't see-thru). Plus the girl has an arrest-warrant out for trying to stop the fishing/hunting of dolphins in Japan, which automatically makes her one of the Good Girls, right?
I'm not sticking Miss Watson into the "Bad Girls" category (which begs the question, what's the difference between Bad Girls and Bad Boys?), but a seemingly nice young girl like her has got to be more careful. Keep your fingers crossed that this won't happen again.
