Avril Lavigne is missing something important on the cover of next month’s Maxim. No, not cliched angst or pedestrian “bad girl” sexuality. They’re both there. It’s not fourteen pounds of hair extensions or lame tattoos, either — they’re there too. It’s the arm with the big pink arrows pointing at it. Either she’s part chameleon, or else her elbow has been surgically fused to the side of her abdomen.
