Taylor Swift has met nearly ever celebrity in Nashville and Hollywood, but even she has butterflies about her first brush with royalty come next month.

"I'm really excited. I'm going to be playing at the Winter Whites Gala at Kensington, so I'm really stoked," the winner of the CMA's Pinnacle Award told BBC 2 Radio Wednesday. "This is my first, like, thing I've performed at for any kind of royal engagement and I'm very, very honored."

The Winter Whites Gala will take place at Royal Albert Hall, and Prince William is said to be attending. Members of the public can buy tickets, and all proceeds will benefit the charity that the prince and Kate Middleton support, Centrepoint, which supports homeless young people.

But Swift, 23, admitted that she has been "asking" around about the protocol for greeting members of the royal family.

"I think I'm just really safe if I just like, shake hands and be polite," she said.

Then, when pressed to discuss what she planned to call the prince, she admitted that she wasn't sure.

"See, I think that's being presumptuous in that, assuming I'll meet them," she explained. "I think first I would just be polite enough to not assume I'm going to get to meet them."
