Jessica Sanchez does her Tina Turner imitation on 'American Idol'

She's up there vamping and working the song; hits the chorus and is off like a shot, like she's channeling Turner. I mean, her vocal skills are unbelievable. I more admire than love the performance; it lacks some sort of emotional connection for me.

"You were a little bit of Tina, a little bit of Beyoncé -- I love seeing you move," says Jennifer Lopez.
