That was fast. A day after quitting the NBC reality show I'm a Celebrity ... Get Me Out of Here! Heidi Montag and Spencer Pratt returned to the jungle set in Costa Rica. Apparently it's difficult for "stars" who live on-camera to live off-camera. Lesson learned. The publicity stunt generated a full news cycle's worth of did-they-or-didn't-they stories. "Super-celebrities don't belong in the jungle. They belong in Hollywood with the paparazzi," Pratt said appropriately.For some context, The Hills couple have quit and un-quit two other times since the show debuted on Monday. This was the closest they came to meaning it.
