"The Hills" starlet Heidi Pratt was abused to the point where she was "convulsively throwing up" and developed a gastric ulcer on the set of the NBC reality show, "I'm a Celebrity...Get Me Out of Here," TMZ.com reported.

Pratt claimed she was confined to a dark room for over 24 hours and fed only water, rice, and beans after she and husband, Spencer Pratt, decided to leave the show, the Web site reported Sunday.

One cast member reportedly told TMZ that the two were treated like detainees at "Guantanamo Bay."

Heidi Pratt was transported to a hospital — where she was diagnosed with a gastric ulcer — after being held overnight in the dark room, according to TMZ. Her husband plans to sue NBC over the show, the Web site also reported.

ITV Studios, which produces the show, denies the report is true.
