Taylor Swift treated fans to a duet with Ed Sheeran as her 2013 North American tour opened.

The singer embarked on the first date of her massive tour in support of her latest album 'Red' in Nebraska last night (March 13).

Swift has enlisted the help of Ed Sheeran to open for her on the dates - and speculation arose that they could duet.

They didn't disappoint, with the pair performing their 'Red' collaboration 'Everything Has Changed' on stage.

Just hours before hitting the stage in Nebraska meanwhile, Taylor Swift uploaded the video for her new single '22'.

The clip sees the pop star having fun with her real-life friends as she hits the beach and prepares to party. Watch Swift and Sheeran duet live below:
