To everyone's great surprise, Prince William took to the stage in London yesterday along with Taylor Swift to sing back up for rocker Jon Bon Jovi. The impromptu performance of the rock classic "Living on a Prayer" was part of a winter-wonderland themed soiree on Tuesday evening to benfit homeless youth.

"He's very funny, really cool," Swift said of the British royalty.

Prior to the performance, Bon Jovi hinted his plan to reporters sharing, "I think he's very fond of singing 'Living on a Prayer.' I know I've read that in the papers before, so we'll see if we get a duet out of him."

The Winter White Gala was thrown in honor of Centrepoint, a London charity that helps homeless youth and was supported by William's mother, Princess Diana. The prince's wife, Duchess Kate, was not in attendance.
