Calm down. Scotty and Lauren are “just friends.”

The prospect of an “American Idol” romance between the show’s two finalists has been flying around the Internet since yesterday morning — after 29 million people saw runner-up Lauren Alaina plant a big, old kiss on Scotty McCreery’s lips moments after it was announced that he’d won the singing contest,

It sure didn’t hurt that they were practically the same age — she’s 16, he’s 17 — and from the same part of the county — the deep South.

“Me and her, it’s more like the brother-sister thing,” Scotty told reporters yesterday.

“She told me before the show she was gonna do that [kiss him] as kind of like a joke. She’s a character . . .

“Really, we’re really close friends. I met her day one of Hollywood Week, and we were schoolmates through this whole experience. She’s great. But yeah, it’s more a brother-sister friendship between me and her.”

“No, we’re not [dating],” Lauren also said yesterday.

“We’re just friends. He is so talented, he has the look, and he sings the same style as me. And he loves Jesus,” she added.
