"I still see Prince George as my nephew," the 27-year-old royal in-law said about the adorable future King of England. "I just want to be the best uncle possible. Like any uncle wants to be, I want to be the cool uncle. The fun uncle… That’s what sort of I’ll always try and be."
While Prince Harry has coolly commanded Apache helicopters, James has pursued the sweeter side of life with his Boomf marshmallow business. The company's founder even created a fun official title for himself as "Wonka-in-chief."
We thought we'd just add the fun throughout the company so the staff in production are 'Boomfaloopas,'" James explained. "We obviously take a lot of sort of magic from Willy Wonka." Still, James said he has yet to find a Christmas gift for little George, saying he hasn't "even gotten that far yet."
During the interview, James had only good things to say about the media attention his family received after Prince George's birth in July 2013. "I think what was the most wonderful thing," he reflected. "Everybody was celebrating with us — for me becoming an uncle and for my parents becoming grandparents. They were all so excited."
The youngest of three — scene-stealing sister Pippa, 31, is the middle child — added that the Middleton family is constantly in communication and gets together "all the time."
While the world gears up for a second royal baby, James provided updates on his pregnant-again big sister's current health condition after she suffered from hyperemesis gravidarum in her first trimester.
She's better," James told ABC News of Kate. "I mean, it's not unknown that she suffered from this acute morning sickness. Fortunately she is, I think, on the mend."
He also remained tight-lipped about whether the couple's second child will be a girl or boy. "It's wonderful to have another niece or nephew on the way," he said.
