Last week, we said goodbye to Rachel Crow, who was devastated, because she’s a little girl, and it was super-depressing. Tonight, though, it’s the semi-finals, and Steve is so excited when he opens the show that his voice actually cracks, haha! Also, for the record, Paula is looking smokin’ hot in a sparkly one-shouldered red dress.First up are the Pepsi Challenge songs, chosen for the contestants by the viewers. This should be fun. Or boring. It’s too soon to tell, really.
