The 76th EE BAFTA Film Awards were attended by Kate Middleton and Prince William.

Before the event, Kate lightly tapped Prince William on the behind.

Vogue captured the moment on Instagram.

Kate wore a one-shoulder white Alexander McQueen gown and long black gloves.

William sported a black suit, a matching bow tie, and polished shoes.

Richard E. Grant and Alison Hammond hosted the event, and Julianne Moore and others presented awards.

Due to scheduling conflicts and Prince Philip's death, the couple missed the previous two ceremonies.

Sunday was their first red carpet appearance as the Prince and Princess of Wales.

Following his mother's death, King Charles III bestowed the titles on them, naming them the new Prince and Princess of Wales.
