Taylor Swift has unleashed the promo clip for her new single.

The pop star is releasing the track '22' from her successful 2012 album 'Red', which spawned hits such as 'We Are Never Ever Getting Back Together'.

Swift debuted the video for the song today (March 13) on Good Morning America only hours before she begins her massive 2013 North American tour.

The clip sees the singer having a good time with her real-life friends as they hit the beach and party together.

As previously reported, Swift has revealed that her upcoming 'Red' tour will see the star perform a more "mature" stage show.

She also teased fans by telling them to expect the unexpected. Watch the video for '22' below:
