Princess Beatrice, who just gave birth to her daughter, Sienna, in September looked like she was glowing alongside her husband, Edoardo Mapelli Mozzi.

Kate's parents, Carole and Michael, also were all smiles outside the venue.

Princess Eugenie, who also gave birth to baby No. 1 in February, stunned in a green coat, which she paired with black boots and stockings.

The belle of the ball! The mom-of-three sported a red coat and dress for the evening.

The night paid tribute to organizations and people who have been helping communities amid the ongoing pandemic.

"We have lost loved ones, seen out frontline workers placed under immeasurable pressure, and we have experienced heart-wrenching isolation from those we hold most dear," she wrote in the program. "Alongside this, we have seen how communities have come together to support those most in need. And through our separation from others, we have been reminded just how powerful human connection is to us all. Just how much we need one another. And how loving and feeling a sense of belonging to one another can provide comfort in tough times. The importance of simply being together."

"In our roles, William and I are so fortunate to meet and spend time with phenomenal people across the country who day-in day-out support individuals and families. And over the past two years, we have been inspired by countless people who have brought their communities together through simple acts of kindness. This Carol Service is our small way of recognising the inspiring contribution so many of you have made. Thank you," she concluded.

Even some reindeer came to the show!

Ultimately, Kate wants to tell people "about the importance of human connection and what it means, as families, communities and as a nation, to be together and to feel united to help one another through times of hardship or uncertainty."
