Rebel Wilson Gets Naughty With Breakthrough Movie Awards Win

'Pitch Perfect' takes away two Golden Popcorns at the 2013 MTV Movie Awards.

The competition was effectively pitch-slapped at the 2013 MTV Movie Awards, as host Rebel Wilson took home the Golden Popcorn trophy for Breakthrough Performance and the "Pitch Perfect" cast won for Best Musical Moment.

Rebel, who will also be seen in the upcoming film "Pain & Gain," was brutally honest in her acceptance speech.

"I only do acting for these awards," she said. "And for cash money."

Then she took it to the next level, going for an awkward exchange with Zac Efron.

"The only thing that would make this better is if Zac Efron took off his shirt right now and came and kissed me," Rebel said, as a confused Efron trotted over with his co-presenters for the next award, Seth Rogen and Danny McBride.

Efron offered Rebel a peck on the cheek, which wasn't good enough for our host.

"You want to give me Australian kiss now? It's like a French kiss but down under," Rebel said.

Clearly, this didn't happen, which was good for 9-year-old Quvenzhane Wallis of "Beasts of the Southern Wild," who was also nominated for Breakthrough Performance. Suraj Sharma in "Life of Pi," Eddie Redmayne of "Les Miserables" and Ezra Miller of "The Perks of Being a Wallflower" were the other nominees in the category.

The reunited Barden Bellas and Treblemakers crew from "Pitch Perfect" opened the Movie Awards with a mashup of Miley Cyrus' "The Climb," Eminem's "Lose Yourself," Alicia Keys' "Girl on Fire" and Macklemore & Ryan Lewis' "Thrift Shop." It was only fitting, then, that the cast later scooped up the award for Best Musical Moment. Anna Kendrick wasn't present, but co-stars Rebel, Anna Camp, Brittany Snow, Alexis Knapp, Ester Dean and Hana Mae Lee were on hand to accept their award.

"We are genuinely such a family and we are so appreciative that you guys even liked this movie 'cause we had such a blast making it, so thank you so much for everyone who liked it," Brittany said.

The other nominees for Best Musical Moment were Anne Hathaway in "Les Miserables" for "I Dreamed a Dream"; Channing Tatum, Matt Bomer, Joe Manganiello, Kevin Nash and Adam Rodriguez for their dance to "It's Raining Men" in "Magic Mike"; Emma Watson, Logan Lerman and Ezra Miller who performed "Come on Eileen" in "The Perks of Being a Wallflower"; and Bradley Cooper and Jennifer Lawrence's dance number in "Silver Linings Playbook."
