Wife of Spencer Pratt was rushed to hospital while filming 'I'm a Celebrity ... Get Me Out Of Here!'

"Hills" star Heidi Montag was rushed to a Costa Rican hospital Saturday after returning to the filming of "I'm a Celebrity ... Get Me Out of Here!" along with her husband, Spencer Pratt, a rep for the couple confirmed to MTV News on Sunday (June 7).

UsMagazine.com originally reported the news, saying that Spencer had traveled to the hospital alongside his wife. A rep for the couple told MTV News that the Us reports were accurate and that he had "no further details at this time."

TMZ, citing unidentified people on the show's set, reported that Heidi was rushed to the hospital after "convulsively throwing up" and was "diagnosed with a gastric ulcer."

The Web site reported that Montag fell ill after she and Spencer had been "held ... in a dark room for a day and a night with only water, rice and beans. It was designed as punishment because they left the show." The couple briefly left the show last week but soon returned, claiming "the devil" had made them leave. TMZ reported that Montag has left the hospital and is receiving medication for her ailment.

Spencer's sister, Stephanie Pratt, took to Twitter to comment on the hospitalization, saying, "I'm really saddened to hear that NBC felt it was OK to punish Speidi so harshly -- and torture them as if they were criminals -- that Heidi was 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. [Please] pray she will be OK.

"Her family is flying out to see her in the hospital," Stephanie continued. "I know they pulled some sh---y antics -- but really NBC?? Too far." On Friday, NBC's executive vice president of alternative programming Paul Telegdy had called Speidi "everything that's wrong with America," adding that in order for the pair to stay on the show they'd be pushed to the limit.

"They are back, and this time they are contrite. ... Yeah, right. What they don't realize is that they are now going to be examined, and their value system utterly deconstructed," he said. "These people really are going to bare their souls."
