The exclusive interview will mark the 30th Anniversary of the Princes Trust.
According to MSN, Ant McPartlin said: "I think someone said they watched I'm A Celebrity so they might know who we are - unlike the Queen. We met her and she didn't know who on earth we were. So granny doesn't know, but they might.
Sidekick Declan Donnelly added: "We're interested in the popular culture thing - what they watch on television, what films and music they like, the human side of things.
"They seem like two very nice guys, ordinary lads who are members of that family. It's particularly interesting for our generation because they are going to be the royals we grow up with, particularly William.�
In other Ant and Dec news, the comedy due will be hosting a new �1million TV game show �The Con Test�.
During the show contestants will have to bluff their way through the answers trying to convince fellow contestants that they know the correct answers.
There will be a run of six shows with a �50,000 prize; winners will enter a grand final with a �1million jackpot.
The show was devised by Ant and Dec who said: "We came up with the idea about two years ago and tried it out on our friends - we played it out in a room upstairs at our local pub.
"It's an exciting game. You don't need great general knowledge, but you need the intelligence to convince the other contestants you know the answers.
The programme will kick off later this year.
