Taylor Swift and Ed Sheeran will take to the stage together for the first time next week when they perform their single ‘Everything Has Changed’ during the Britain’s Got Talent live final on June 8.

Following on from Jennifer Lopez’s controversial performance of ‘Live It Up’ earlier this week, show organisers have announced that Best friends Taylor and Ed will be taking to the stage to give what will no doubt be a tamer performance compared to J.Lo’s racy offering.

The dynamic duo, who are currently travelling together on Taylor’s tour, will sing their collaboration ‘Everything Has Changed,’ which features on the country hitmaker’s latest album ‘Red.’ So far this series, Britain’s Got Talent has enjoyed appearances from J.Lo, Demi Lovato and Olly Murs who will be performing on tonight’s show.

Taylor and Ed will no doubt be hoping to attract less controversy which J.Lo has experienced in the last week following her daring performance on Tuesday, which saw her dance around the stage scantily-clad in a tight black leotard and thigh-high leather boots.

The singer’s performance has received more than 100 complaints from media watchdog Ofcom, who say that they are looking into the situation. Ed recently gushed about touring with Taylor revealing that she is playing the perfect hostess to members of her crew.

“She’s great to be on tour with, she treats me and the crew very well. I’m really enjoying the tour,” Taylor told HollywoodLife.

Speaking on Taylor’s songwriting talents, Ed continued: “I think you sing about what you know. There’s nothing worse than singing a song that has no relevance to you, and all the songs she’s singing have a deep relevance to her. “They’re all personal.”
