Spencer, Heidi Pratt quit NBC's 'I'm a Celebrity'

Recently married The Hills stars Spencer and Heidi Pratt have reportedly quit NBC's 'I'm a Celebrity... Get Me Out of Here!'

Upset at the show's Costa Rican jungle living conditions, the newlyweds quit the NBC reality competition hours after it began filming this weekend, NBC reality chief Paul Telegdy confirmed Monday.

The duo had earlier briefly quit the competition twice during its first 24 hours. However, this time and ostensibly final time, the couple vowed to abscond from Costa Rica after being unable to rough it.

It remains unclear how the show plans to handle the couple's reported departure, however Daniel Baldwin -- the older brother of I'm a Celebrity participant Stephen Baldwin -- is already in Costa Rica and set to join the show as a replacement for Spencer, according to a website. Heidi's sister and fellow The Hills regular Holly Montag is also reportedly currently 'on a plane to Costa Rica' to replace Heidi, said the website.
