Scotty McCreery could be most popular 'American Idol' ever, says Nigel Lythgoe

scotty-mccreery-homecoming-gi.jpgThe youngest-ever finalists -- Lauren Alaina, 16, and Scotty McCreery, 17, -- take the stage for the two-night finale, beginning Tuesday, May 24.

In a half-hour interview the only time executive producer Nigel Lythgoe is quiet -- and looks genuinely perplexed -- is as he considers which teenager will be crowned Season 10's "American Idol."

"If Scotty wins, I believe he could be the biggest 'American Idol' selling artist of all time," Lythgoe tells Zap2it.

"Whoever it is, the fact is, it's America's vote."

But when you have had a season with a diverse array of artists, where will the Casey Abrams, Jacob Lusk and Paul McDonald fans shift their alliance?

"I don't know who James' votes will go to," Lyhtgoe says of James Durbin, who left two weeks ago. "I don't know who a rocker votes for in who's left. I truly don't know. You've got two country [singers] there."

Lythgoe does remain impressed by Haley Reinhart, who made it to the Final 3 despite numerous appearances in the Bottom 3.

"I don't know what Haley's genre was," he says. "She doesn't have a genre. She's slightly old-fashioned, slightly jazzy, but if you take her individual tracks off of iTunes, she sounds very much like Adele."
