In the clip — filmed back in 2010 for ITV News — Wills is adorably talking about his future wife, when he lets slip that she has a “naughty” sense of humour.
The whole revelation comes as he described the fact they met at university and were friends for over a year before anything romantic happened between them.
“She’s got a really naughty sense of humour, which helps me because I’ve got a very dirty sense of humour,” he told the news outlet.
The remark appeared to be a bit of a private joke, with Kate adorably giggling and looking at her future hubby.
It came after he described how their romance had “blossomed” thanks to the fact they always had a good “giggle”.
Talk about cute.
The now Duke and Duchess of Cambridge have melted hearts of fans with the newly emerged footage, with many commenting on how “in love” they looked.
“The way he looks at her makes me melt,” one user wrote underneath.
The pair — who married in April 2011 — now have three kids together, Prince George, five, Princess Charlotte, three, and four-month-old Louis.
