Check out photos of the most controversial reality show contestants of all time.

The duo quit for good after the live portion of last night's show, another source told, which first reported the news.

Not that the cast will miss them: During one of the Pratt's temper tantrums, the other celebrity contestants ransacked Heidi's belongings and stole her dry shampoo.

Once the newlyweds came back to the campsite, an enraged Spencer smacked a water bottle from the hands of Frances Gallier, one half of the Vh1 comedy duo Frangela.

Pratt also hid wrestler Torrie Wilson's bag away from the campsite in retaliation.

Explaining his actions, Heidi said: "My husband is a very new Christian."

The Pratts solicited prayers on Twitter before taking off for the jungles of Costa Rica.

"I'm so excited to be in God's nature!" Heidi posted.
