Their special Christmas carols concert later this month will now be shown on ITV, according to The Sun.
The service, on December 14 at Westminster Abbey, had reportedly been due to be broadcast by the BBC.
Although William normally doesn’t draw controversy, a body language expert has explained how he does have a coping strategy to “calm down” at testing moments.
US-based body language expert Blanca Cobb analysed William and Kate’s engagement interview for Express.co.uk.
Prince William’s ‘nervous’ moment with Kate and his strategy to ‘calm down’
Angry: Cambridges and other royals hit out at BBC
She said: “In this video William is a little nervous.
“If you watch his hands, he’s rubbing his fingers. And when you’re when one part of your body rubs another part of your body, you’re soothing yourself. You’re calming yourself.”
The interview was filmed in 2010, the year before the Cambridges tied the knot.
From the beginning of the couple’s chat with journalist Tom Bradby, William can be seen rubbing his hands.
Ms Cobb said: “It’s like when we were little, and we fell down and got hurt, Mummy would say, ‘oh honey, that’s okay, let Mummy kiss it or let Mummy rub it and it’ll go away’.

“Mum’s not coming up to us kissing our booboo but what we’ve done is we adapted that sensation.
“So that way we will do it to ourselves to help calm us down. And it shows in different ways.”
Ms Cobb also said William and Kate showed a “formality” in their interview.

She compared the Cambridges’ interactions to footage of the Duke and Duchess of Sussex in their engagement interview in 2017.
William and Kate sat apart, whereas Harry and Meghan sat close together and were holding hands.
Ms Cobb said: “Kate, she’s looking towards his direction, but initially she wasn’t looking at him.
“It’s not that there’s a physical distance in between the two of them, it’s just more formal than it was with Harry and Meghan.
“They’re looking at each other. They’re smiling, but I would just say that with Meghan and Harry, it’s much more evident.”
She added that it is clear William and Kate love one another but that they “show affection in public differently”.
