On Tuesday, the Duke and Duchess of Cambridge shared news of a secret event that was hosted at their Kensington Palace home earlier this month.

The parents-of-three shared photos of the private event to Instagram on Tuesday, which was held to honor Radio 1's Teen Heroes of 2019 and was attended by popstar Camila Cabello and BBC Radio 1 DJs Clara Amfo and Greg James.

The 10th annual awards help recognize some of the most inspirational teens in the United Kingdom, whether they're advocating for social issues or fighting their own medical adversities. This is the fourth year in a row that the inspirational honorees have been invited to the palace.

Of course, the Duchess of Cambridge stunned for the event, opting for an L.K. Bennett Coral Print Midi Dress for the occasion. The $645 silk dress is still available to shop!

"Hearing the incredible things these Teen Heroes have done is so inspirational," Cabello said about the event. "Their passion and dedication to help others is amazing and they really blew me away."

The post on Tuesday comes just a few days after the couple wrapped up their five-day royal tour of Pakistan.
