Taylor Swift duets with Steven Tyler

Taylor Swift has added Steven Tyler to her list of onstage guest stars during her 1989 World Tour after the pair duetted in Nashville, Tennessee.

The Aerosmith rocker joined Taylor for a rendition of his iconic hit I Don't Want To Miss A Thing at the Bridgestone Arena on Friday (25Sep15).

He was in Nashville as he is due to perform at Franklin's Pilgrimage Festival on Sunday (27Sep15).

In a post on Instagram.com, the Bad Blood hitmaker shared a photograph of the duo performing, alongside the caption, "The incredible @iamstevent tonight singing 'I Don't Want to Miss a Thing'. Magical things going down on this tour. #1989tournashville"

Steven wrote on Twitter.com that the show was "epic", adding "until next time..."

And he wasn't the only guest star at Friday's gig - country singer Kelsea Ballerini performed Love Me Like You Mean It with the Shake It Off hitmaker, and Alison Krauss sang When You Say Nothing At All with Taylor accompanying her on piano.
