Look out, Kate Middleton. Taylor Swift has formally met your man.
The 23-year-old artist actually met Prince William yesterday at the Kensington Palace in London, as Swift was in town for the Centrepoint Winter Whites Gala.
That's not all. The two later collaborated musically. We kid not!
The highlight of the event? Jon Bon Jovi taking to the stage with his guitar, flanked by Swift and William, for an acoustic version of "Livin on a Prayer."
And Taylor took the stage and joined in! And then so did Prince William! Talk about an unexpected musical threesome - one as legendary as it was surprising.
Watch the performance you'll likely never, ever see again:
