Although James has had the account since 2013, he has only recently made it public for fans to see. He proves to be quite an animal lover and an outdoorsy type in his feed, which also features a photo of his other sister Pippa after they cycled over 3000 miles together to raise money for the Michael Matthews Foundation.
