Avril Lavigne returns with the first single to be taken from her new album, 'Goodbye Lullaby'.
It's been almost four years since we last saw the Canadian singer behind the massive hit, 'Sk8ter Boi' in the chart, but she's back for 2011 with a new single.
The video was shot at the end of 2010 in 3D as part of a three day long video shoot.
