Prince William Sings With Taylor Swift and Bon Jovi in Unlikely Trio

Taylor Swift looked like a princess, Jon Bon Jovi strummed his guitar, and Prince William let loose. Together at a fundraiser at Kensington Palace in London, the three joined forces on stage to give a performance of viral proportions

The video, below, shows the Duke of Cambridge and T-Swizzle providing backup vocals as Bon Jovi sings his 27-year-old rock hit "Livin' on a Prayer" (yes, it was released in 1986, three years before Swift was born). The song recently resurfaced on Billboard's Hot 100 singles chart after a sports fan's lip-syncing antics went viral last month.
