Avril Lavigne does seem able to stay forever end: The song sticks to the "Complicated" formula, the video is set at a high school prom, and she's still a sk8tr girl. And despite the super prominent Radiohead references don't expect this video to look any different from what you might expect from the pop-rocker.
If anything, the '90s influence here seems to be more Hole "Miss World" than anything Radiohead...
