The Cambridges enjoyed a rare evening out on Friday, strolling hand-in-hand down the red carpet when they put in a surprise appearance at the London Palladium. The royals were catching a performance of Pantoland and the Duke gave a speech on stage.

Kate opted for a gorgeous dress from one of her go-to designers, Alessandra Rich. The printed style boasted on-trend puff sleeves and a flattering midi cut.
