Prince Harry and Pippa Middleton were on hand to attend the splashy Boodles Boxing Ball at London's Grosvenor House Hotel.
The annual charity gala, which is now in its fourth year, benefits a foundation for terminally ill children and a trust for injured soldiers.
Prince George's 29-year-old uncle looked sleek and chic in a tuxedo as he made his way inside the gala.
Meanwhile, Middleton, 30, who arrived separately with beau Nico Jackson, stunned in a pleated saffron skirt and crisscross black bodice.
The couple were the guests of honor at the event.
Other A-list attendees included Harry's pregnant cousin Zara Phillips, as well as track-and-field Olympian Jessica Ennis and soprano star Katherine Jenkins.
