Listen to Taylor Swift on iHeartRadio | Listen to Bon Jovi on iHeartRadio

Taylor Swift met Prince William at the Winter Whites Gala at Kensington Palace on Tuesday — and together they provided Jon Bon Jovi with some backing vocals for a special performance.

The singer looked regal in an elegant white gown as she chatted with the famous royal, and the pair later took the stage to join the rocker on “Livin on a Prayer.”

The event was put on by Centrepoint, a charity William supports that works to “build a brighter future for homeless young people.”
