Taylor Swift looked positively radiant while attending the Winter White Gala at Kensington Palace Tuesday evening.

Dressed in an elegant white gown with an intricate lace bodice, the 23-year-old looked downright regal at the black tie affair.

The "I Knew You Were Trouble" singer greeted Prince William shortly before performing for the 200-person audience during the charity dinner.

T.Swift recently opened up about how thrilled she was for the rare performance.

"I'm really excited," she said during a radio interview with BBC Radio 2. "I'm really stoked. It's the first royal engagement I've done and I'm very, very honored.''

The country star also admitted that she's been brushing up on her etiquette skills so that she's fully prepared when she's around the royal family.

"I think I'm just really safe if I just shake hands and be polite," Swift explained. "I think that's being presumptuous in assuming I'll meet them, so first I'm going to be polite enough to not assume I'll meet them.''

Bon Jovi is also slated to perform. Once the concert ends, William will give a short speech and present Jon Bon Jovi with the Centrepoint Great Britain Youth Inspiration Award for his humanitarian work.

The event will raise money for Centrepoint, a charity providing housing and a range of other services to young homeless people in the U.K.

Prince George's father has been a patron of the organization since September 2005.

And while the Palace was being transformed into a winter wonderland, the 31-year-old Brit and Prince Charles visited the London Zoo to check out the facility's latest conservation project.

The two royals briefly walked by the tiger enclosure, making sure to maintain a cautious amount of space between them and the glass wall.
