Ranvir Singh and Christine Lampard are hoping to interview members of the royal family as they take it in turns to host ITV show Lorraine.
The presenters are replacing Lorraine Kelly on her self-titled morning show while she takes her usual summer break from presenting duties.
Good Morning Britain host Singh told Hello magazine her dream guest would be eight-year-old Prince George.
“I love having kids on, and it would be interesting to hear what he thought about wearing a suit at Wimbledon,” the 44-year-old said.
The mother-of-one added: “Children of that age are very switched on, and it would be fascinating to hear how much he knows about his role in life.
“I’d also like a conversation with the Queen. She holds so many secrets, a Pandora’s box that will never be opened.
“I’m an ambassador for domestic violence charity Refuge and think Camilla is great, too, raising awareness of domestic violence through Safe Lives.”
Loose Women panellist Lampard, 43, revealed she is a big fan of the Duchess of Cambridge.
The former One Show presenter said of Kate: “She’s fantastic and I truly believe she was destined to become queen.
“I can’t imagine anyone doing a more fantastic job than her. What I’d most like to ask her is about the ordinary side of her life, at home away from the cameras.”
The duo, who will be presenting separately, promised to make a distinctive mark on the show.
Singh said: “I’m quite sarcastic and enjoy a bit of banter.
“My favourite stories are the quirky ones and I embrace chaos.”
Mother-of-two Lampard added: “I get a weird thrill when something doesn’t go to plan.
“Throughout the summer we’ll be like the naughty prefects and when the new term starts in autumn the head girl will return.
“Until then I feel a sense of responsibility looking after Lorraine’s ‘baby’.”
Lorraine is on ITV weekdays from 9am.
