Sunday night at the MTV Movie Awards, Holly Montag told the Dish Rag that her sister Heidi Montag was doing great in Costa Rica, that she and Spencer were competing against each other but that they had formed a "secret alliance."

"I know she's gonna win. I have seen my sister build fires and eat ants. … That was growing up, for fun. She has a much better chance than anyone is giving her credit for," Holly told us on camera.

But this morning, news broke that the newlyweds tried to quit NBC's "I'm a Celebrity … Get Me Out of Here!" the first day they arrived in Costa Rica to shoot the "C-listers in distress" reality show, which premieres today.

"They wanted to be treated like stars," a source on the series told E! News' Ryan Seacrest. "[Spencer] literally thought he and Heidi were staying in a Four Seasons, working out and getting a tan."

The two refused to eat the same food as everyone else and complained about their lower-wattage costars like Janice Dickinson, actors Stephen Baldwin and Lou Diamond Phillips, former NBA player John Salley and "American Idol" castoff Sanjaya Malakar. An NBC exec reportedly had to coax the newlyweds to remain on board.

"I wish they got some real celebrities like K-Fed," Montag reportedly whined.

Hmm. Color us suspicious, but we think we're all being played. Who ya gonna believe, the NBC leak, guaranteed to make us want to watch the show tonight?

Or her sister, who says Heidi has more survival skills than anyone of us can even dream of?

We're going with the family report. Spencer and Heidi aren't quitting, trust us! They are way too smart for that.
