Pratt, Montag quit 'I'm A Celeb' for fourth time

Spencer Pratt and Heidi Montag have quit I'm A Celebrity...Get Me Out Of Here! for a fourth time, it has been reported.

The couple made their latest decision to leave the show because of Montag's recent hospitalisation, Access Hollywood reports.

"We gave it our all in the camp, but now it's about health. Doctors are going to be with her for the next three days. At the end of the day, we went back in and proved to ourselves that it wasn't just about us - it was a life-changing experience," said Pratt.

The Hills star also admitted that he was not prepared for the competition.

"We've never really lived in a jungle! I thought we were all going to be chilling at your hotel, we'd come to the jungle, we make drama, we'd do all these crazy stunts, we'd sleep on cots for a little bit, we'd go back.

"No-one told us we were really guinea pigs," he added.

Yesterday, it was reported that Montag's younger sister Holly will enter the Costa Rican jungle in an upcoming episode.
