MTV Joins 'I'm A Celebrity' Reality Show, Featuring Heidi And Spencer

Network will re-air NBC show on Sundays, starting June 7, with new footage and real-time commentary.

This summer on NBC, 10 celebrities will be dropped into the middle of the Costa Rican jungle, where they'll battle challenges — and one another — as they struggle to survive and take home the title of King or Queen of the Jungle.

The show is called "I'm a Celebrity ... Get Me Out of Here!," and NBC and MTV have announced a partnership to promote the relaunched reality show, which premieres June 1 at 8 p.m.

The celebrity lineup has just been announced. Castmembers include "Hills" stars Heidi Montag and Spencer Pratt, former Detroit Pistons player John Salley, supermodel and reality personality Janice Dickinson, sixth-season "American Idol" contestant Sanjaya Malakar, "The Usual Suspects" actor Stephen Baldwin and professional wrestler Torrie Wilson.

The hosts of the program, in addition to other celebrity contestants, will be named soon.

During the show, viewers will have the opportunity to control the fates of the contestants, challenging them with various tasks in a quest to win food, supplies and luxury items. Celebrities will be playing for the charity of their choice. The winner of the entire competition will nab a big cash prize.

The NBC/MTV partnership will have both networks jointly casting for the show and cross-promoting the series on air. Every Sunday, starting June 7, MTV will air a marathon of the previous week's episodes, including new footage and real-time commentary from castmembers.

"We're always looking for innovative ways to bring great content to our viewers and to build our stars," said Tony DiSanto, head of MTV programming. "This partnership with NBC is a symbiotic model where our talent gets a different platform on a broadcast network and we get an exciting new series in real time. In this ever-changing media landscape, it's important to seek out fresh and efficient ways to create and present content — blow up models, break barriers and challenge the norm."
