Getting to work on her new “Rock N Roll” music video, Avril Lavigne showed up in Palmdale, California last night (July 25).

The “Sk8er Boi” babe looked gorgeous in a military/punk fusion ensemble as she filmed scenes with “Wonder Years” actress Danica McKellar (she played Winnie Cooper on the beloved show).

Meanwhile, Avril’s previous single “Here’s to Never Growing Up” was just certified platinum here in the US, and she couldn’t be happier.

Lavigne, who recently married Nickelback rocker Chad Kroeger, tweeted, “Here's to Never Growing Up reached a million downloads in the USA!!!! Here's to going platinum! Thank you to all my fans!!”
