Prince William rocks out with Bon Jovi and Taylor Swift

The Artist Currently Known as Prince — Prince William, that is — took to the stage in London with Taylor Swift to sing back up for Jon Bon Jovi.

The impromptu performance of “Living on a Prayer” was part of a winter-wonderland themed soiree on Tuesday night that benefited a charity for homeless youth.

The occasion allowed Swift, America’s music princess, to meet English royalty in the ultimate regal setting: The prince’s home in Kensington Palace.

“He's very funny, really cool,” Swift told reporters about Will.

Britain's Prince William, The Duke of Cambridge, speaks with singer Taylor Swift during a charity dinner at Kensington Palace on Tuesday.

The Duke of Cambridge appeared to enjoy the meeting but was heard begging off from any potentially embarrassing performance.

“As long as you don't want me to get up there and do any dancing or backing vocals,” he told Swift.

She had other plans for the prince, and Bon Jovi seemed game to go along.

“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,” he told reporters before he and other entertainers took to the stage.

The trio rocked out at the event, which benefitted homeless teens.

Swift pulled the reluctant duke from the audience and, after taking a moment to compose himself, he rocked out in the most noble manner possible beside the music duo.

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, did not attend.

Swift, who looked quite princess-like in a white chiffon column gown with an embellished, form-fitting bodice, appeared to enjoy the evening, although she apparently had a difficult time understanding everything said to her, according to a tweet by a reporter for “The Times” of London.
