The Princess of Wales has admitted her children were "very sad" to miss the Royal Variety Performance in London, which she and the Prince of Wales attended.
Prince William and Kate made their first appearance at the event since her recovery from cancer.
Wednesday's red carpet show at the Royal Albert Hall was headlined by the cast of Paddington The Musical.
After arriving and being presented with posies by nine-year-old twins Emelia and Olivia Edwards, the family of staff at a care home for entertainment industry workers, Kate asked if they were fans of Paddington Bear.
The princess, wearing a green velvet gown, then told the girls that her children were "very sad" not to attend the show and added she had to tell them children were not allowed to go.
"My kiddies were very sad, we're going to have to keep it a big secret that I saw you guys," she said.
"They were very sad not to be joining us."
It is the sixth time William and Kate have attended the annual charity event.
When Olivia told the prince, wearing a tuxedo, her favourite singer was Billie Eilish, he replied she had good taste.
He said: "It's very nice to see you both. You're very smiley, you two."
The royals were also greeted on the red carpet by ITV board members and representatives from the Royal Variety Charity, of which the King is the royal patron.
The Paddington cast were set to take to the stage on Wednesday evening, while pop star Jessie J and Grammy award-winning singer Laufey were also expected to perform.

Held annually, the Royal Variety Performance was first staged in 1912 for King George V and Queen Mary in support of the charity, which helps those working in the entertainment industry.
Ahead of the show, its executive producer Giles Cooper said the charity was "thrilled" the prince and princess would "once again attend the Royal Variety Performance".
Mr Cooper, also chairman of the charity, added: "This annual great British institution, viewed by a worldwide TV audience of over 150 million, continues to be a crucial fundraising event supporting people in all areas of performance, either on or off stage.
"In this pressurised world of working in the entertainment industry, our mental health initiative, started in 2024, has been a lifeline for many who are experiencing issues such as anxiety, depression or addiction."
On Tuesday, the princess called on businesses to value "time and tenderness just as much as productivity and success" in her first speech since she was diagnosed with cancer at the start of 2024.
Speaking at the Future Workforce Summit, Kate told 80 business leaders: "Every one of you interacts with your own environment; a home, a family, a business, a workforce, a community.
"These are the ecosystems that you yourselves help to weave. Imagine a world where each of these environments were built on valuing time and tenderness just as much as productivity and success.
"As business leaders, you will face the daily challenge of finding the balance between profitability and having a positive impact. But the two are not, and should not be incompatible."
