Royals Royal Roar! Princess Kate and Prince George Go Dinosaur Hunting: 'George Looked So Happy' The royal toddler enjoyed a mommy-son day out at the Natural History Museum s dinosaur galleries in London By Monique Jessen Published on October 26, 2015 04:10 PM Share Tweet Pin Email Photo: Chris Jackson/Getty; John Stillwell/PA Wire Once again, Princess Kate and Prince George are getting their roar on. In the middle of a busy few days at work last week, Kate squeezed in some mommy time, taking her "lively" 2-year-old son to see the dinosaurs at the Natural History Museum in South Kensington on October 22. “She was holding George’s hand, showing him around and talking to one of the people who worked there,” says fellow museum-goer Rimi Rahman. “People didn’t really notice her at all,” adds Rahman. “They went all around the dinosaur gallery – George looked so cute and little, his hair is so nice. He looked so happy.” Confirming the visit, a museum spokesperson tells PEOPLE, “We were very happy to welcome Natural History Museum Patron HRH the Duchess of Cambridge for a private visit last Thursday.” Known for their world-famous dinosaur gallery, the museum features a roaring Tyrannosaurus rex as well as Dippy the Diplodocus – a 292-bone skeleton cast that’s more than 69.8 feet long and 13.9 feet high. The impressive replica was commissioned by Kind Edward VII and has been the centerpiece in the museum’s enormous Hintze Hall for many decades. It was in the Hintze Hall that Kate was spotted holding George’s hand as she showed him the ancient fossils and displays. Looking casual in black-and-white print capri pants with black ballet flats (George in blue jeans with a white polo shirt under a dark blue sweater), the adorable duo went mostly unnoticed as they enjoyed their day out. This is at least the second time Kate has taken George to the museum, which is just a short drive from the family’s London home at Kensington Palace. The young prince enjoyed a day out at the museum just before he turned 1, when Kate and Prince William chose the museum’s butterfly exhibition as a backdrop for his official first birthday photographs. And it’s definitely not the first time that the mother-son duo have enjoyed special bonding dates out in London. Kate has taken George to several tourist hot spots during the past year, including the Science Museum and a festive trip to London s Winter Wonderland in Hyde Park last Christmas.
