Scheming reality stars Heidi Montag and Spencer Pratt have signed on to join the cast of NBC’s I’m A Celebrity… Get Me Out Of Here!, a rep for the reality stars revealed to Access Hollywood on Friday.

This summer, the stars of MTV’s smash reality hit The Hills will join other C-list celebs in the jungles of Costa Rica for four weeks on the US spinoff of the long-running British series of the same name.

Looks like the devious Speidi will be in good company on their latest reality TV excursion. On Tuesday, NBC announced that Rod Blagojevich will be featured on the summer series. The impeached Illinois governor was removed from office in January after allegations that he tried to sell the state’s empty Senate seat following the election of President Obama.

I’m A Celebrity… premieres on NBC June 1.

What do you think of how the cast is shaping up so far?
