Reality's Most Unlikely Couple: Sanjolly!

It almost goes without saying that the replacement of prayer-happy priss Heidi Montag by her down-to-earth sister Holly Montag on I'm a Celebrity... Get Me Out of Here! was a bit of sweet relief to both fans of the NBC show and the celeb contestants in the Costa Rican jungle. And while the Hills star has made friends with all her fellow stranded stars, sources tell OK! she's gotten very close to one of them in particular — former American Idol finalist Sanjaya Malakar!

"They've been spending a lot of time together," the source tells OK! about the unlikely pair. "She's even admitted to having a little crush on him!"

If that doesn't have you scratching your heads, how about this — they've already come up with a nickname for themselves.

"Sanjaya and Holly created the name 'Sanjolly' sometime earlier this week," says that source.
