American Idol semi-finalist Didi Benami impressed the most important American Idol judge of them all last night, Simon Cowell. In fact, Simon disagreed with Randy Jackson and said that her entire performance was a "wow moment."

Simon said, "I thought that was head and shoulders above anything else we’ve heard tonight."

Didi faced harsh criticism last week, but she just picked up her guitar, sang, and strummed along as she performed "Rihannon" by Fleetwood Mac. She has a great personality and a commercial voice. Go Didi.
