PENNSYLVANIA: Taylor Swift says Britain’s Prince William convinced her to join him and Jon Bon Jovi on stage for a performance. The trio famously collaborated on the rock band’s hit ‘Livin’ On A Prayer’ - one of the Duke of Cambridge’s favourite karaoke tracks - and she insisted he asked her to join him. She explained: ‘Jon Bon Jovi got up to perform and he called Prince William out because he’d heard he loves singing ‘Livin’ On A Prayer’ on karaoke nights. Prince William looked at me and said, ‘I’ll do it if you do it.’–EXPO
