God, this song kicks so much ass.
It's so fierce, seeing as I just discovered it i'm going to say it's the best pop/punk song of 07 so far! I think it came out in 06 though.
Never really been a fan of her, but this song has way more pop sensibility to it then her past stuff. Though I liked that song she did with Pink alot too.
If you want to hear it check it out with the video clip here for free: Though low quality, in HQ the song is amazing.

Mainstream pop needs more people like her, she's gross at times but damn original and fun/exciting. She has the attitude which first attracted me to Gwen.
