We knew Prince William would be a perfectly polite host, but it was only this week that the world learned of his karaoke skills, and perhaps his secret desires of being a rock star. At the Winter Whites Gala in London, the prince joined Taylor Swift and Jon Bon Jovi for an acoustic performance of Bon Jovi’s hit “Livin’ on a Prayer” that went viral. The encounter topped off a massive week for Taylor, who had huge success at the American Music Awards on Monday — she took home four honours, including the event’s top prize for Artist of the Year, the third time she’s won it. Another big talking point at the AMAs was Katy Perry’s opening performance of “Unconditionally,” or more specifically her Geisha-inspired stage costume, which some critics thought was on the racist side.
On a lighter note, Australia welcomed the cast of Anchorman 2: The Legend Continues for a star-studded Sydney premiere, where Will Ferrell, Steve Carell, Paul Rudd and David Koechner broke out an a cappella performance of “Afternoon Delight.” And over in Mexico, Hollywood lovebirds Diane Kruger and Joshua Jackson got a head start on their Thanksgiving celebrations by lounging poolside at their resort.
