Taylor Swift's Super Bowl-winning beau Travis Kelce PERFORMS with her in London

Travis Kelce shocked fans as he joined Taylor Swift onstage at a sold-out Wembley this evening - in front of the likes of Fleabag's Andrew Scott and Sir Paul McCartney. It is the first time the pair have taken to the stage together, after officially announcing their relationship on Instagram on Friday evening. The couple have never featured on each other's social media accounts until Taylor posted an adorable photo of herself and Travis posing with the Prince of Wales and his two children - Prince George and Princess Charlotte. Tonight the American footballer joined Taylor onstage during the song I Can Do It With a Broken Heart. He was dressed up in a white bow tie, tailcoat and top hat and powdered Taylor's face as part of the act.
