Prince George, Princess Charlotte and Prince Louis make their red carpet debut at pantomime show

Much to the delight of royal fans, the Cambridges have made their first red carpet appearance as a family!

The Duke and Duchess of Cambridge stepped out with Prince George, seven, Princess Charlotte, five, and Prince Louis, two, at a special pantomime performance at the London Palladium.

The family of five went to see Pantoland, a holiday-themed pantomime show sponsored by the National Lottery, held for frontline workers and their families.

All three of the Cambridge kids looked excited as they walked the red carpet, with Louis grasping his mother's hand while Prince William held the hands of Charlotte and George.

For the family night out, the children dressed up, with George wearing a red and blue sweater to match William's red sweater with a navy blazer.

Charlotte donned a grey and blue checkered dress which complimented Kate's navy blue dress.

But it was Louis' outfit that really stole the show: the Prince stepped out in a gorgeous blue wool jacket.

Prior to the show, Prince William delivered a short speech in which he thanked the audience.

He said: "We are here tonight for a very special performance. Special, because of you—the key workers here in the audience.

"You have given your absolute all this year, and made remarkable sacrifices. So too have your families, who I’m sure have seen far less of you than they would have liked. It’s lovely that you are all here together tonight."

The event marked the children's first official appearance since their cameo on the BBC’s Comic Relief fundraising program, Big Night In, back in April.

It also marked their very first time sitting in the Royal Box as well.

Too cute!
