Queen Elizabeth's footsteps and trying out their hand at vlogging, with the launch of their own YouTube channel. The royal couple christened the new Duke and Duchess of Cambridge channel with a 25-second introductory video composed of a montage of footage of them at various public events and galas over the years, including overseas tours, attending the BAFTAs, and meeting Sir David Attenborough. There's also previously unseen footage of members of the royal family, including Queen Elizabeth and their three children, Prince George, Princess Charlotte, and Prince Louis. In the opening of the clip captioned âBetter late than never - we're now on YouTube,â William jokes to his wife, âYou'll have to be careful what you say now, because these guys are filming you,â to which Kate replies while a big laugh, âI know!â The Duke and Duchess of Cambridge also included a comedic outtake from a special message they recorded for St. Patrick's Day during which a concerned Kate tells her husband, âYou didnât need to roll your Râs,â as William replies, âDo I not?â
