'X Factor': Alex & Sierra's 'Toxic' is one of the best auditions we've seen


Alex and Sierra - The X Factor by caseycarlsonx1

A schmoopy couple named Alex and Sierra came out on "The X Factor" Season 3 premiere and totally had us thinking they were going to be one of those joke auditions that Simon laughs off the stage.

However, their quirky, coffeehouse version of Britney Spears' "Toxic" was awesome. We want to download that and put it on our iPod.

Demi says of the performance, "I have the chills all up and down my legs. Not only are you talented, but you're so down-to-earth" and Simon adds, "I thought this was going to be quite corny when you first came out, but actually you're both cool and you're quirky. I thought it was an incredible version of the song."

Paulina and Kelly both also praised their love and chemistry together. What did you think of Alex & Sierra?
