Lauren Alaina is Carrie Underwood Jr. on 'American Idol'

Lauren Alaina is doing Carrie Underwood's "Flat on the Floor." She's sassy, has some attitude and the vocal chops.

I guess this is who she is. Not sure why people would prefer her to Carrie, but whatever. Little messy, its a bit all over the place. 

"I thought it was amazing y'all," Randy Jackson says. Steven Tyler loved it, too, "the sky's the limit." Jennifer Lopez says "that's what you have to do."
