"Heidi and Spencer are still in the jungle and part of the show," their rep told Access Hollywood.
And though two people thought to be Spencer and Heidi were photographed covered in blankets arriving at LAX Tuesday night, Access Hollywood has learned that it was actually Spencer's younger sister, Stephanie Pratt, and his friend with a very similar name, Spenser, acting as decoys to throw off the paparazzi.
"Super-celebrities don't belong in the jungle. They belong in Hollywood with the paparazzi," Spencer said while appearing to leave the show for a third time on Tuesday.
"We're gonna miss you guys," Heidi told her fellow contestants before exiting camp. "But call us when you get back to LA."
As previously reported on AccessHollywood.com, Spencer was "begging" that he and his wife be allowed back on the show, a source close to the production told Access Hollywood's Billy Bush.
But, according to "I'm A Celebrity" rules, the couple cannot come back on the show unless the cast agrees. America may also be asked to vote on whether they can come back as well.
Additionally on Tuesday, the show source told Access that Holly Montag, Heidi's sister and fellow "Hills" castmate, may be joining "I'm A Celebrity."
"Holly is on a plane [to Costa Rica]," the source said.
The source added that Holly is "appalled at what her sister faced" in the jungle thus far and she wants to redeem the family name for charity.
Daniel Baldwin, brother of current jungle-dweller Stephen Baldwin, is also heading to the jungle and is expected to join the cast, the show source said.
