#1 without a doubt: Tom Cruise. Loathe the man.
Runner's-up:
*Paris Hilton [she cannot actually be classed as an "actress" though, so she's not really eligible.] If it were a choice between her life and the life of that poor chihuahua she drags around, the dog wins hands-down.
*Colin Farrel: it was dislike-at-first-sight. Why is this guy considered cool? Why is he considered to be a great actor? Its one of those mysteries of the universe.
*Katie Holmes: this silly **** almost wrecked BB for me. Anyone this stupid deserves instant death; and if you don't believe me, read a few of her interviews. NO BRAIN, WHATSOEVER. Why must stupid people be first to breed...? but que sera, sera... her face looks deformed, and her baseless arrogance annoys me to no end. Not cool. [and therefore, the perfect mate to my #1 choice.]
*Angelina Jolie: just go away, already. When your career is not about your talent, but is instead about whose man you managed to steal *this* week, its basically over. Go away.
*Halle Berry: its all been said before, so many times.
