'Hills' stars 'desperate for Celeb return'

Hills co-stars Spencer Pratt and Heidi Montag are reportedly desperate to return to I'm A Celebrity...Get Me Out Of Here!.

The reality stars had made two failed attempts to exit the Costa Rican jungle since their arrival last week, before finally walking out for good following the second episode.

Pratt had told his fellow campers: "As much as Speidi is going to miss all of you, that challenge just proved to us we do not have what it takes."

However, the aspiring rapper has since taken to his Twitter account to plead with network executives to let the couple return, writing: "The devil fooled Speidi in to making an awful decision and we are praying to Jesus to get NBC to give us another shot to redeem."

Speaking to Access Hollywood, a production insider explained that show rules meant it would be up to the remaining cast to decide whether or not the pair could return, and that it could also be put to a public vote.

The source added that Montag's younger sister Holly is currently en route to Costa Rica and could step in as a replacement for her departed sibling.
