Slumdog Milllionaire, Twilight

Teen romance — whether with vampires or in Mumbai slums — is all the rage at the 2009 MTV Movie Awards.

Twilight leads this year's field with seven nominations, just edging out the six-time nominated Slumdog Millionaire. Both are up for Best Movie.

Joining the two in the Best Movie race are The Dark Knight, High School Musical 3: Senior Year and Iron Man.

Slumdog and Twilight will duke it out in three other categories: Breakthrough Performance Male (Dev Patel vs. Robert Pattinson), Best Kiss (Patel and Freida Pinto vs. Pattinson and Kristen Stewart) and Best Song — a new category.

The films' leading ladies were also singled out. Pinto is pitted against Miley Cyrus (Hannah Montana: The Movie) and Vanessa Hudgens (HSM 3), among others, in Breakthrough Performance Female. Stewart will face off with Oscar winner Kate Winslet (The Reader), Angelina Jolie (Wanted), Anne Hathaway (Bride Wars — not Rachel Getting Married) and Taraji P. Henson (The Curious Case of Benjamin Button) for Best Female Performance kudos.

Heath Ledger earned two posthumous nods for The Dark Knight: Best Villain and Best Fight, in which Christian Bale is also nominated.

In addition to Best Song, the show also added a Best WTF Moment category, honoring such zany scenes as Jason Segel's naked breakup in Forgetting Sarah Marshall.

Andy Samberg will host the show, airing live May 31 at 9 pm/ET.
