What the hell? Avril Lavigne tweeted the cover for “Smile,” her second single off her fourth LP Goodbye Lullaby, today, and on it she’s got some serious Medusa weave going on.

Whatever the case may be, at least least the tatted-up Canuck has got the smiling bit down. Head below to hear the Max Martin/Shellback-produced jam.
