James Middleton wants to be the "coolest" uncle to Britain's Prince George.
The 27-year-old businessman - who is brother to Catherine, Duchess of Cambridge, 32, - has admitted that he wants to be his nephew's best friend, although he doesn't know what to get the 16-month-old royal for Christmas.
Talking on ABC's 'Good Morning America' on Wednesday (12.11.14), James said: "I still see Prince George as my nephew and want to be the best uncle possible.
"Like any uncle I want to be the cool uncle, I want to be the fun uncle. What shall we get him for Christmas this year, how can we stand out?
"I think there's a long way to go to be a cool uncle. I'm trying to be as best as I can."
The entrepreneur - who was promoting his confectionery company Boomf - revealed that his sister is feeling better after suffering from hyperemesis gravidarum during her second pregnancy.
Referring to Catherine, who is reportedly due in April, James said: "She's better. It's not unknown she's suffering from acute morning sickness, fortunately I think she's on the mend."
He also shared his favourite moment from his sister's wedding to Prince William in 2011.
James shared: "The most wonderful thing about that wedding which will stay with me forever was that although billions were watching, it felt like a family wedding.
"My little treat for them was to give them a puppy and Lupo was their gift."
