Brad Pitt, Kim Kardashian and Peter Dinklage just joined the long list of celebrities presenting, "Catfishing," or otherwise making a ruckus at the MTV Movie Awards Sunday (April 14). Rebel Wilson will make her awards show hosting debut, as presenters like Liam Hemsworth, Melissa McCarthy, Amanda Seyfried, and Adam Sandler hand out Golden Popcorn trophies to their peers.

Here are some of the moments you won't want to miss:

Rebel Wilson hosts 
Her pre-hosting duties have already entailed straddling Channing Tatum and holding firecrackers up to her bustier. Sunday night she'll perform a live mashup with her "Pitch Perfect" castmates, and do ... well, goodness knows what else. One thing's for certain, she'll make you laugh so hard you spit.

Brad Pitt presents Movie of the Year
The "World War Z" star will cover up his gray hair and present the most coveted Golden Popcorn of the night to one of these worthy nominees: "Silver Linings Playbook," "Ted," "Django Unchained," "Marvel's The Avengers," and "The Dark Knight Rises."

Kim Kardashian introduces Selena Gomez
Selena will perform her new single "Come and Get It" for the first time on TV. Prediction: Kim's baby bump will steal the spotlight before Selena ever takes the stage. 

Peter Dinklage presents to Will Ferrell
Dinklage will present the inaugural "Comedic Genius Award" to Ferrell. Warning: MTV may be playing a little fast and loose with the word "genius" in this instance.

Celebrity "Catfish"
During the official pre-show, a three-way "Celebrity Catfish" will be revealed between "Ted" star Mark Wahlberg, "True Blood's" Joe Manganiello and "Pitch Perfect's" Anna Kendrick. Manti Te'o, eat your heart out.

Hot new category
MTV always has the most fun award categories. This year the Movie Awards introduce ... Drum roll, please: Best Shirtless Performance. Bow-chicka-wow-wow. The nominees are Christian Bale ("The Dark Knight Rises"), Daniel Craig ("Skyfall"), Taylor Lautner ("The Twilight Saga: Breaking Dawn -- Part 2"), Seth MacFarlane as Ted ("Ted"), Channing Tatum ("Magic Mike").
