Avril is mentioned near the beginning in the movie "Music and Lyrics" which is a cheesy, formulaic romantic comedy... exaclty why I loved it!!!
Hugh Grant (plays a has-been 80s pop star) and Brad Garrett (his manager) are talking about Hugh's character writing a song for a rising pop star and Hugh complains he can't find a good lyricist to write with and Brad goes:
"Alright look, I know it's not easy to get somebody good this fast. Okay, but there's this guy, supposedly he's very hip, very edgy. He just worked with Avril (proounces it "Ahvreel")."
I thought it was pretty hilarious
