'Vampire Diaries,' Justin Bieber Lead Teen Choice Award Nominations

'The Avengers,' 'The Vow,' Katy Perry and Adele also land multiple nods.

The nominations for the 2012 Teen Choice Awards have been announced, and the CW's hit drama "The Vampire Diaries" snagged a leading six nominations, with "American Idol" and Justin Bieber following close behind with five each.

"Diaries" earned nominations for Choice TV Show: Fantasy/Sci-Fi, Choice TV Actor: Fantasy/Sci-Fi nods for both Ian Somerhalder and Paul Wesley, and Choice TV Actress: Fantasy/Sci-Fi nominations for Nina Dobrev and Kat Graham. Somerhalder is also vying for Choice Male Hottie against Bieber, multi-nominee Ryan Gosling, Liam Hemsworth and Robert Pattinson.

The Choice Female Hottie contest pit pals Katy Perry and Rihanna against Miley Cyrus, Selena Gomez and model Kate Upton.

Among the other top TV nominees are "Pretty Little Liars," "Gossip Girl," "Supernatural" and, oddly, "Bones," and HBO's racy "True Blood," which is up for Choice TV Show: Fantasy/Sci-Fi and Choice TV Actress: Fantasy/Sci-Fi for Anna Paquin.

All of the usual candidates are among the top film nominees, with "Twilight Saga: Breaking Dawn - Part 1" scoring nominations for Choice Movie: Sci-Fi/Fantasy, Choice Movie Actor: Sci-Fi/Fantasy for both Robert Pattinson and Taylor Lautner (who is also up for Choice Movie Actor: Action for "Abduction"), and Choice Movie Actress: Sci-Fi/Fantasy for Kristen Stewart.

They face stiff competition in the Sci-Fi categories against "The Hunger Games," which landed nominations for Choice Movie: Sci-Fi/Fantasy and acting nominations for leads Jennifer Lawrence and Josh Hutcherson, and "The Avengers," which along with its Choice Movie nominations scored individual acting nods for Chris Hemsworth, Robert Downey Jr. and Scarlett Johansson.

Among the other top film nominees are "The Help" (Choice Movie: Drama and Choice Actress: Drama nominations for Emma Stone and Viola Davis), "The Vow" (Choice Movie: Drama, Choice Actress: Drama for Rachel McAdams and Choice Actor: Drama for Channing Tatum, who is also up for his comedic performance in the much-nominated "21 Jump Street") and, inexplicably, the released-today comedy "What to Expect When You're Expecting," which earned four nods, for Choice Movie: Comedy, Choice Actor: Comedy for Chris Rock, and Choice Actress: Comedy nods for both Cameron Diaz and Jennifer Lopez.

On the music side, the Choice Single by a Female Artist nominees are "Set Fire to the Rain" by Adele, "Stronger" by Kelly Clarkson, "Dance Again" by Jennifer Lopez featuring Pitbull, "Part of Me" by Perry and "Eyes Open" by Taylor Swift. On the guys' side are Bieber ("Boyfriend"), Drake ("Take Care"), Flo Rida ("Good Feeling"), Bruno Mars ("It Will Rain") and Pitbull ("Give Me Everything [Tonight]").

Many of the same artists will vie for Choice Male Artist (Bieber, Drake, Mars, Pitbull and Blake Shelton) and Choice Female Artist (Adele, Lopez, Perry, Rihanna and Swift).
