The Duke and Duchess of Cambridge attend the screening of Sir David Attenborough's Natural History Museum Alive 3D.

The Duke and Duchess of Cambridge wore 3D glasses as they watched a "groundbreaking" new film by naturalist and broadcaster Sir David Attenborough. Their Royal Highnesses attended the premiere of Natural History Museum Alive 3D, which sees Sir David hide away inside the museum after dark, only to find its exhibits coming to life around him.

The film, which will be broadcast on Sky at 6.30pm on New Year's Day, features dinosaurs, giant apes, and 118ft (36m) snakes, with the evergreen naturalist explaining how scientists can understand their lives by studying their bones.

The Duchess, wearing a floor-length black lace Alice Temperley dress, chatted and joked with Sir David in the main hall of the Natural History Museum in the shadow of a Megatherium skeleton - or giant ground sloth - which exits the film by burrowing its way out of the cafe.

The event was The Duchess's first engagement as Patron of the museum in London's Kensington. The couple then took their seats with 300 other guests in the main hall, under the whip-like tail of the museum's reproduction Diplodocus skeleton "Dippy".

The dinosaur, built from five different partial skeletons, came to England from America after King Edward VII, then the Prince of Wales, requested it on a visit to the Carnegie Museum.

Kate Middleton traded princess duty for mom duty in London Wednesday when she took baby Prince George for a walk — and we have the exclusive pictures! Kate and William's dog Lupo also came along, as the Duchess of Cambridge pushed the future king of England in his stroller. The trio enjoyed the fresh air in Kensington Gardens, which is basically their backyard. Just yesterday we saw the new royal mom decked out in a tiara that once belonged to the Queen Mother. Will and Kate took up official duties on Tuesday, joining the queen for the annual diplomatic reception. But for her time with George, Kate swapped the traditional headpiece for a baseball cap and donned some sneakers, looking like an everyday mom.
