Photographer reveals he got 'apprehensive' Kate Middleton to dance for royal portraits

The photographer behind the already iconic 40th birthday photos of Kate Middleton has revealed he made the Duchess of Cambridge dance for him. 

Paolo Roversi, who took the three portraits of Kate released by the Royal Family to mark her milestone birthday, said the mum-of-three was "apprehensive" at first about doing the photoshoot. The pair initially met at Kensington Palace for tea and biscuits to discuss the process. 

"Every day she is machine-gunned by photographers but not used to posing," Roversi told Italian newspaper Corriere della Sera, per Hello Magazine. 

Roversi, who has previously worked with supermodels like Naomi Cambell and Kate Moss, said Kate was "a bit fearful about facing a real session," which would require about four hours of work. 

"But once she started it would be very easy, I reassured her," he said. 

The photographer said he wanted to "take pictures in motion" and given the "wonderful wide skirt" Kate donned for one of the looks, he "made her dance in front of his lens". 

"[It was] a kind of accelerated waltz mixed with a pinch of rock 'n roll," he explained. 

Roversi added that he captured the Duchess in natural light, with "little makeup, no hairstyle, simple earrings, a ring." 

"The focal point of Kate's face is her gaze and smile," he said.
