LOS ANGELES — This year's MTV Movie Awards will be a showdown between a bevy of bridesmaids and a cast of killer kids.

"Bridesmaids" and "The Hunger Games" top nominees at MTV's annual film honors with eight nods apiece, including bids for best cast, breakthrough performance and movie of the year. Rounding out the best-picture contenders are "Harry Potterand the Deathly Hallows: Part 2," ''The Help" And "The Twilight Saga: Breaking Dawn-Part 1."

MTV announced nominees Monday in 12 categories, including six new ones such as "best on-screen dirtbag" and "best gut-wrenching performance." Also new this year: Nominees were selected by a panel of actors, producers, agents and industry tastemakers instead of via online vote from the public.

Fans can still choose the winners, though. Voting begins online Tuesday at 8 a.m. Eastern time.

The 21st annual MTV Movie Awards will be presented June 3 at the Gibson Amphitheatre in Universal City and broadcast live on MTV.
