Meanwhile, co-host Romesh Ranganathan drew criticism from online fans after he took aim at Wills and Kate’s kids George, six, Charlotte, four and little Louis, one.
“Like me you’re blessed with three kids… I imagine every morning they come running into your bedroom and you look at their beautiful faces and say, 'I regret this'," Romesh quipped.
Fellow co-host Rob Beckett then joined in on the action by making a comment about the Duke and Duchess having to find a babysitter.
“Thank you for coming out tonight. You’re on date night. That's exciting,” Rob said.
“You got the babysitter until midnight or 1am? It's worth that extra 20 quid."
While the Duke and Duchess appeared to be unfazed by the jokes and even laughed out loud, some viewers took to Twitter to share their concerns over the comments.
“Poor Wills & Kate having to force laughter for these 2 idiots,” one person wrote.
Another person wrote: “Wow @robbeckettcomic and @RomeshRanga hosting the royal variety is painful.”
