Celeb 'Catfish' Comes To MTV Movie Awards Pre-Show!

Tune in Sunday at 8:30 p.m. ET to see Mark Wahlberg fall victim, plus a 'Show With Vinny' sneak peek and more red-carpet goodness.

Which celebrity would you most like to "mistakenly" hook up with online? During Sunday's MTV Movie Awards pre-show at 8:30 p.m. ET, Mark Wahlberg, Anna Kendrick and Joe Manganiello fall victim to the first-ever three-way celebrity Catfish, captured by no less than "Catfish: The TV Show" stars Nev Schulman and Max Joseph.

This special installment of "Catfish" — not to mention all our live red-carpet coverage on the Sony Pictures Studio lot — leads up to the 2013 MTV Movie Awards at 9 p.m. Sunday. Watch a sneak peek of the unbelievable case of (multiple!) mistaken identities below.

Before Sunday's big event, pre-show hosts Josh Horowitz, Karlie Kloss, Vinny Guadagnino and Christina Garibaldi will provide viewers with exclusive behind-the-scenes access to the MTV Movie Awards red carpet. Horowitz and company will also conduct interviews with attendees, presenters and winners throughout the entire ceremony.

The Sunday night broadcast will offer plenty of other surprises and exclusives, including an advanced look at "The Show With Vinny," in which "Jersey Shore" alum Guadagnino, his mother Paola and uncle Nino sit down for a candid conversation with "Pain & Gain" stars Mark Wahlberg and Anthony Mackie. On that same episode, which will air in full Sunday at 11 p.m. following the ceremony, Ke$ha makes an appearance to promote her new MTV series "Ke$ha: My Crazy Beautiful Life," and she leaves her glittery trademark on Nino in a way only the iconoclastic pop singer can.

There's still plenty of time before Sunday's ceremony to vote for your favorite performers in categories that only MTV could offer, including Best Musical Moment and Best Scared-As-Sh-- Performance. Tune in this Sunday at 9 p.m. to see which of your favorite stars take home top honors!
