Avril Lavigne has unleashed her new single.

The Canadian is releasing the track 'Here's To Never Growing Up' as the flagship single from her forthcoming new album.

The singer has been teasing the song over the past week and the track has now been released to iTunes.

The single sees Lavigne give an ode to Radiohead as she proclaims the benefits of living a youthful life.

The singer is due to unleash the song's accompanying video in the near future and she has teased the clip with a prom-themed still, which can be seen below.

Her new album, which will mark the follow-up to 2011's 'Goodbye Lullaby', has yet to receive a title or release date.
