Theron, Garfield to present awards
Charlize Theron and Andrew Garfield are among the stars handing out gongs at the 2012 MTV Movie Awards.
The South African actress and the Amazing Spider-Man star will be presenters at the star-studded US ceremony, alongside their co-stars Emma Stone, Chris Hemsworth and Kristen Stewart.
Shame star Michael Fassbender, Friends With Benefits' Mila Kunis and Contraband's Mark Wahlberg will also be on presenting duties on June 3.
The Hunger Games and Bridesmaids lead the battle for the gongs, with eight nominations each, including a best female performance nod for leading ladies Jennifer Lawrence and Kristen Wiig.
Jonah Hill's comedy 21 Jump Street and Harry Potter And The Deathly Hallows Part II both follow in second place with six nominations.
Harry Potter stars Rupert Grint and Emma Watson are among those nominated for Best Kiss, for Ron Weasley and Hermione's long-awaited clinch in the final film, but they face competition from Jennifer and her Hunger Games co-star Josh Hutcherson, and last year's winners, Twilight stars and real life item Kristen Stewart and Robert Pattinson.
New awards this year include Best On-Screen Transformation, Best Gut-Wrenching Performance and Best Cast.
Horrible Bosses co-stars Jennifer Aniston and Colin Farrell will go up against each other for Best On-Screen Dirtbag, along with Jon Hamm for his portrayal of Kristen's arrogant lover in Bridesmaids.
The 21st Annual MTV Movie Awards will take place on June 3 at the Gibson Amphitheatre in Universal City, California, before airing on June 4 on MTV.
