While the exact details of the tiny tot's celebrations aren't yet known, she will be in the UK for the special event, joining her parents and brother as she travels to the UK for the first time in honour of the Queen's Platinum Jubilee.

Harry and Meghan recently visited the Queen on their way to the Netherlands for the opening ceremony of the Invictus Games, but they left their children, Lili and son Archie, three, back in California, where they have settled since stepping back as senior working members of the royal family.
The couple will not be joining the Queen on the Buckingham Palace balcony during Trooping the Colour, as this year's gathering will be limited to working royals.

Making the announcement, a spokesman for Buckingham Palace said: "After careful consideration, The Queen has decided this year's traditional Trooping the Colour balcony appearance on Thursday 2 June will be limited to Her Majesty and those members of the Royal Family who are currently undertaking official public duties on behalf of the Queen."
