James Durbin is first up as "American Idol" cuts to its final four. He's asked to go start a group on the far side of the stage....
Lauren Alaina is next. She'll be in her own group as well. And indeed, she starts her own group.
And now we're gonna go listen to Jennifer Lopez get up and sing "On the Floor" (but not be judged).
Man, she puts on a show. There are guys in glass boxes, lasers, fire, dancers, videos -- the whole enchllada. Can't stop watching. She's shimmying on a rising platform, wearing shiny sequined harem pants and a silver beaded corset top with fringed epaulets by Zuhair Murad. She's totally intense, almost a bit scary. Can hear she's a bit out of breath, too.
Big smile at the end. There's the J.Lo we know from the show.
