"The Perks of Being a Wallflower" star is up for three Golden Popcorns, including Best Female Performance, Best Kiss and Best Musical Moment, for her performance as Sam in the stirring, coming-of-age adaptation, written and directed by Stephen Chbosky.
"I am so excited to have been nominated for three MTV Movie Awards for 'Perks of Being a Wallflower'!" the 22-year-old said. "I love the show and I love this movie! I'm so thrilled."
In the Best Female Performance category, Watson will face fellow thesps Anne Hathaway ("Les Misérables"), Mila Kunis ("Ted"), Jennifer Lawrence ("Silver Linings Playbook") and Rebel Wilson ("Pitch Perfect"), who's also starring as the night's host.
In the Best Kiss category, Watson and co-star Logan Lerman will smooch-off against Kerry Washington and Jamie Foxx ("Django Unchained"), Kara Hayward and Jared Gilman ("Moonrise Kingdom"), Jennifer Lawrence and Bradley Cooper ("Silver Linings Playbook"), and Mila Kunis and Mark Wahlberg ("Ted").
And in the Best Musical Moment, Watson, Logan and Ezra Miller will battle Anne Hathaway ("Les Misérables"); Channing Tatum, Matt Bomer, Joe Manganiello, Kevin Nash and Adam Rodriguez ("Magic Mike"); Anna Kendrick, Rebel Wilson, Anna Camp, Brittany Snow, Alexis Knapp, Ester Dean and Hana Mae Lee ("Pitch Perfect"); and Bradley Cooper and Jennifer Lawrence ("Silver Linings Playbook").
Rounding out "Perks" four nominations is Breakthrough Performance, which Miller garnered for his turn as gay teen Patrick.
