Rob Pattinson - Do 15 year old girls really find him dreamy? If his ugly mug weren't enough, I would think his incredibly lax standard of hygiene would ruin the appeal.
Kristen Stewart - Horribly untalented for the high-profile movies she has appeared in/is set to appear in. I hate her "woe is me" attitude regarding her fame and the public's interest in her relationship with Rob.
Perez Hilton - Arrogant to the extreme, and so self-satisfied with the fact that he has crossed the threshold from anonymous internet blogger to media personality. Hate that he inflates his influence, acting as though he can take credit for Lady GaGa's success and as though he was ahead of some trend in realizing her greatness. I happen to remember listening to Just Dance and reading about her on ATRL several months before he first mentioned her in June 2008.
Katherine Heigl - Another case of a celebrity who is entirely too ungrateful for her success and celebrity. Quit badmouthing the show that gave you an ounce of relevance, as well as your movie roles. She has some comedy talent, but she's too ****y to be liked.
Megan Fox - Attractive, but only in a trashy "straight guy fantasy girl" way, and ungrateful of the films that launched her into super-stardom.
Ashton Kutcher - Hardly a celebrity at this point, but I can never forgive him for the douchbaggery he unleashed upon the world during his Punk'd days.
Kimora Lee Simmons - Has an inflated sense of her importance. You were a hot commodity for about a year in the modeling world, at least with Karl Lagerfeld, but the fashion industry quickly grew tired of you. Now you're the empress of a trashy Baby Phat clothing line and you have weird creases on your neck that bug the hell out of me.
Barbara Walters - Crochity and arrogant, continually abrasive to your guests on the View.
Carrie Prejean - Not a celebrity, but how can you not hate this hypocrite?
Elizabeth Hasslebeck - Always running her mouth about subjects that are obviously too complex for her to comprehend. Has yet to communicate anything articulately.
Candy Spelling - Continually expresses dismay with her daughter's decision to openly discuss their bad relationship through interviews and tell-all books, then turns around and does exactly the same thing. Team Tori.
John Mayer - Better known at this point for attention whoring than for writing notable music.
Dane Cook - Banal frat boy humor that is based too heavily on jittery gimmicks and silly faces. Let's not even mention the attempts as a serious musician.
Unable to handle criticism.
Kanye West - For obvious reasons.
