Taylor Swift has revealed what is like singing karaoke with Prince William.

Swift’s royal encounter occurred when she attended a charity gala hosted by the Duke and Duchess of Cambridge back in November 2013.

The ‘22’ singer joined Prince William and Jon Bon Jovi to perform a karaoke version of Bon Jovi’s ‘Livin’ On A Prayer’.

Taylor Swift has now spoken about her duet with England’s future king for the first time.

In an interview with the Mail on Sunday’s Event magazine the country star explained how the unlikely trio came together:

“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, too', and then he took my hand.”

She went on: “I was surprised and flattered and it felt surreal and completely natural at the same time. We jumped on stage and started to sing and we were really yelling into the microphone and clapping hands. I still can't believe I've sung with Prince William.”

The ‘All Too Well’ songstress admitted that both she and William were “more screaming than singing”, but was still complimentary about the prince’s voice:

“Even through all that I could hear his voice and it is pretty good. A nice tone. I'd definitely say he's got star quality, and if he ever wants me to sing with him again I'll be there.”

Taylor Swift is currently on the European leg of her ‘Red’ world tour. Tonight (February 2) she play’s London’s O2 Arena.
