The celebs I really can't stand and wouldn't mind if someone else beat them up for me are:
Jennifer Lopez (because of her snobby/too celebrity like behaviour's getting old)
The Olson Twins (it's just annoying to see them together all the time. I mean we get it, they're close but still get some new friends)
Mandy Moore (too sugary sweet) she's pretty though, I'd love to have skin like her.
The Back Street Boys
'N sync
the whole mass produced-talentless-mindless boy/girl bands.
for example orlando bloom does deserve his fame after he fell out of that window and broke his back. to go through that and to be told you would never walk again, must have been tough on him. However, he pulled though and now acts in massive action movies.
BUT, people like Kelly Osbourne, Russell Crow and hilary duff are just brats with attitude problems. they dont deserve the fame and money they have!
