Kate Middleton video explains a rather bizarre confusion around Prince Louis
We now know how to say Prince Louis.
Last week Duchess Kate gave birth to her and Prince William's third child, Louis.
And while much of the hysteria is behind us, a week on, not every question has been answered.
Although the TV cameras might have stopped rolling, many are still confused about one thing - but we're not quite sure why.
Is it Louis as in Lewis, or is it Louis as in Loo-ee? Yep, that's the question that many have been asking since the announcement of the royal baby's name.
Well, it looks like we may finally have the answer for those people in the form of Will and Kate's wedding video.
If you skip to 4.30 in the video from 2011, she'll explain just exactly how to pronounce her third child’s name.
So there we have it. It's Louis as in Walsh, Theroux, Vuitton and King Louis XVI.
Good to know!
