Taylor Swift sings with Prince William, Bon Jovi - watch the video
During the gala, Swift got up on stage sang "Livin' on a Prayer" with rocker Jon Bon Jovi -- and the Prince joined in. Cue all the squeeing. All the squeeing in the world. She tells NBC News in the video below that Wills is "very funny, very cool."
Who wasn't in attendance? The Prince's wife, Catherine, Duchess of Cambridge. NBC News speculates that it's because Prince William wanted the focus to be on the charity and not his beloved wife, but also -- they do have a four-month-old at home. Maybe she wanted a quiet night home with the baby.
Either way, the video is below. Check it out. That lucky Taylor Swift.
