'Twilight' or 'Harry Potter'? Kristen or Emma? Teen Choice Awards Air Tonight

"Twilight" or "Harry Potter"? Kristen or Emma? Lady Gaga or Katy Perry? Decisions, decisions. The 2011 Teen Choice Awards screen air Sunday on Fox at 8/7C, and it's sure to be as tense as a chance run-in between a werewolf and a vampire (or, if you prefer, a bespectacled wizard and Lord Voldermort).

Taylor Lautner, Robert Pattinson and Kristen Stewart are all nominated for Choice Movie Actor and Actress in Sci-Fi and Fantasy. Daniel Radcliffe and Emma Watson are also nominated on those respective categories, and "Twilight" will be going head-to-head with "Harry Potter and the Deathly Hallows: Part I" in the Sci-Fi/Fantasy Movie category.

Will we see a repeat of the MTV Movie Awards, in which "The Twilight Saga: Eclipse" swept the competition?

Voting for the awards cosed Friday. Who did you vote for?
