Taylor Swift not only got to mingle with royalty this week at the Winter Whites gala at London’s Kensington Palace, she also got to sing “Livin’ On a Prayer” with both Jon Bon Jovi and Prince William on-stage.

Swift and Bon Jovi performed at the gala to benefit a charity dear to the Duke of Cambridge, Centrepoint. However, the crowd got a lot more than just solo performances from the Red singer and Bon Jovi.

An attendee posted a video on Instagram with the caption “Classic Tuesday night with Jon Bon Jovi performing 'Living on a Prayer' with Taylor Swift and HRH,” which showed the trio singing karoke-style to the hit song.

Since then, a much more clear version has emerged on YouTube, E! Online notes.

After the fun performances, Prince William, whose wife Duchess of Cambridge and baby Prince George were at home, presented Bon Jovi with the Centrepoint Great Britain Youth Inspiration Award.
