Heidi Montag, who was in Costa Rica shooting I’m A Celebrity… Get Me Out Of Here, was rushed to a hospital earlier today for an undisclosed medical problem.  NBC reportedly allowed Spencer Pratt to leave the show’s jungle set to accompany Heidi to the hospital.

Earlier today, NBC’s executive vice president of alternative programming, Paul Telegdy told reporters that the producers had been playing a “psychological experiment” on the couple after they threatened to leave the show earlier in the week.

Paul explained that the pair were placed in a dark secluded cell together for several days.  He said,

When we cut the lights, we have them on infrared cameras, and all we can say is you see two sets of very terrified eyes, blinking, goggle-eyed, terror-struck! They prayed quite vigorously.

No word yet on whether or not the seclusion had anything to do with Heidi’s emergency.

Update: Spencer’s sister Stephanie just tweeted,

Rushed to the hospital and has an IV in her arm after being locked in a dark room for 3 days w no food or water. Pls pray she will be ok…

Sources are saying that Heidi is suffering from some sort of infection. Her family is currently en route to the Costa Rican hospital where Heidi is currently being treated.

Update #2: Sources on set are now saying that Heidi has been diagnosed with a gastric ulcer.  According to the sources, NBC executives first tried to tell Heidi not to go to the hospital, but finally sent an ambulance when she insisted.  Heidi was released from the hospital after treatment last night, and is now on medication.

Some anonymous cast or crew members are comparing the set of the show to Guantanamo Bay. One person has told reporters that other cast members have also threatened to quit the show, but NBC has been holding their passports. In addition, apparently the contracts that all cast members signed before going on the show required them to stay the entire time.
