Allison Iraheta on Kimmel: 'Oh yeah!'

Last night found American Idol fourth-place finisher Allison Iraheta performing on Jimmy Kimmel Live! The rocker did her hot, screw-you single “Friday I’ll Be Over U,” and I must say, she’s really coming into her own as a performer. See for yourself here:

I feel like people will continue to sort of compare her to P!nk, but whatever. This girl’s got style, a cool look, a good voice, and crazy-fun hair. And I feel like her signature “Oh yeah!” screams are especially good here.

What do you think, PopWatchers? Are you impressed with Allison’s performance? Is “Friday I’ll Be Over U” in your iPod rotation?
