"I just want to be the best uncle possible, like any uncle wants to be," James, 27, told Good Morning America's Amy Robach Wednesday. "I want to be the cool uncle, the fun uncle!"
As for sister Kate, who is pregnant with royal baby No. 2? "She's on the mend," said James, referring to the duchess' recurrent bout with severe morning sickness.
He wouldn't say whether she's expecting a girl or a boy—just that "it's wonderful to have another niece or nephew on the way." He was also tightlipped when Amy said, "We've heard Kate's coming to New York."
"I've heard that too," said James laughingly. He fumbled a moment over that one, before he claimed, "I don't really know..."
Fair enough. So Kate's a maybe in the U.S., but Boomf is definitely here! James, whose official title is "Wonka-in-Chief," confirmed the U.K.-based company has officially launched on this side of the pond. So if you're in the market for marshmallows with your personal pictures on them, James Middleton is your man!
Note to Harry: You might want to step it up in the sweets department!
