Irish American Idol hopeful Siobhan Magnus blew the TV critics away last night with her rendition of Chris Isaak's "Wicked Game."

"The highlight of the night was undoubtedly Siobhan Magnus' performance of Chris Isaak's "Wicked Game."

So says MTV's Kyle Anderson adding that she deserved extra credit for taking on such a difficult tune.

Judge Ellen also liked Siobhan's performance saying it was "good enough to forget this was a singing competition."

Lindsay Parker on had this to say: "Siobhan completely floored me tonight. I was stunned by her huge voice and smoky tone.

"I personally thought "Wicked Game" really displayed her wicked stylistic range. I'm keeping my eye on this girl."

Of course crotchety judge Simon Cowell said it was a bit dark and dismissed Siobhan as "a funny little thing."

Yeah, well, he'll be the one with egg all over his face when she makes it through to the next round.

You go Siobhan!
