Stephanie Pratt, on Twitter, claims that the couple were locked in the so-called “lost chamber” for 3 days without food or water.

NBC denies the allegations. “ITV Studios, producers of the series, state that press reports at this time are untrue,” an ITV rep told Access Hollywood in a statement. “ITV has been producing this format around the world for many years and the health of the celebrity participants are of the utmost importance. A medic and a doctor are present at the location at all times for all participants. All allegations of the celebrities being deprived of food and water are completely untrue.”

In reality, the couple spent only one night – not three — in the NBC show’s Lost Chamber, from 4:30 PM on Thursday until around 6:30 AM on Friday. The stars actually spent three days in hotels after quitting the show for a third time on Monday.

The Pratts have actually spent most of their “I’m A Celebrity” time indoors, unlike their co-stars.

Heidi is recovering in a hotel room after being admitted to a Costa Rican hospital for a possible stomach ailment.

I have a feeling that Heidi and Spencer’s definition of torture is a lot different than most, especially after the premiers shampoo bottle incident.
