‘Catfish’ At The MTV Movie Awards: Watch Now!

Mark Wahlberg, Anna Kendrick and Joe Manganiello get caught in a celebrity 'Catfish' during Movie Awards.

Rebel Wilson has been one busy lady, preparing to host the 2013 MTV Movie Awards and setting up romantic dates with some of Hollywood’s hottest.

Or has she? That’s what “Catfish” hosts Nev Schulman and Max Joseph helped MTV’s Josh Horowitz find out during the MTV Movie Awards pre-show.

You see, Horowitz has been in a year-long online relationship with Wilson (or, more likely, someone purporting to be Wilson) and has yet to meet his love in real life. So he enlisted MTV’s resident dating detectives to aid him in discovering the true identity of his Internet paramour. What they uncover is a tangled web — one ensnaring actors Mark Wahlberg, Anna Kendrick and Joe Manganiello. In short, it’s the first celebrity Catfish.

Of course, this all leads up to the big show: the 2013 MTV Movie Awards, airing live at 9 p.m. ET. In addition to her hosting duties, Wilson will reunite with her “Pitch Perfect” co-stars, including Anna Camp and Skylar Astin, for an aca-awesome mash-up performance that’s not to be missed, while Selena Gomez and Macklemore & Ryan Lewis will also rock the Sony Pictures Studios lot with their new singles. In addition, a trio of the silver screen’s finest will be recognized with special tributes. Emma Watson will receive the Trailblazer Award, Will Ferrell will be honored with the first-ever Comedic Genius Award and Jamie Foxx will take home the Generation Award.

And stick around after the show for a sneak peek at Vinny Guadagnino’s new series “The Show With Vinny,” airing at 11 p.m. ET.
