Last night, Prince William joined Jon Bon Jovi and Taylor Swift on stage for a surprise performance of Livin' On A Prayer at a charity gala in Kensington Palace.
No biggie, right...(?!?!)
Let's be honest - Wills doesn't exactly look like he's having the best time ever (bit shy, isn't he?), but we think he does a great job of releasing his inner rock god. Sort of...
Taylor spoke to reporters about the Winter Whites Gala, which supports homeless charity Centrepoint, and said: "It's positively magical here. There are fairy lights and there is fake snow falling from the sky and everything is just gorgeous. I am just very lucky to be here.
"I don't think I have ever played in a palace before. So it will be really wonderful. This evening is so special... It is for a charity that as well as being very important to Prince William is also very important to me."
The country popstar added that Wills "was really funny" and "so cool".
Wills, who left wife Kate Middleton at home with baby George, has been a patron of Centrepoint since September 2005, following his mother Diana in supporting the charity.
