UPDATE: This video from the actual Gala is incredible -- check out Taylor, Bon Jovi and Prince William belting out "Livin' On a Prayer" together!
Taylor Swift has finally met a Prince -- Prince William, that is!
The country cutie is set to perform at the Duke and Duchess of Cambridge's palace, which has been transformed into one magical winter wonderland for their Winter Whites Gala.
Swift looked stunning as she arrived to Kensington Palace in London on Tuesday. The "Begin Again" singer wore a fitting white ball gown with a sparkly, sheer bodice for the "Doctor Zhivago"-themed affair. She styled her hair in a romantic side-swept updo and sported her signature bold lip.
The event is being held to benefit the homelessness charity, Centrepoint, which Prince Williams works very closely with.
The 23-year-old -- who will headline the event -- will be joined by Youth Inspiration Award-recipient Jon Bon Jovi and James Blunt on stage.
Other musical acts included singer Eliza Doolittle, violinist Charlie Siem, and the dance troupe Flawless ... which is exactly how Taylor looks.
