Prince Harry and Meghan Markle will tie the knot on May 19, 2018.
But their official consent from Queen Elizabeth was not received until two months before their royal wedding, as reported by All Cute All The Time.
The loved-up pair is set to wed at St. George’s Chapel at Windsor Castle.
Harry and Meghan, who first met in July 2016 on a blind date set by a mutual friend, announced their engagement on November 27, 2017.
The couple has been busy preparing for their upcoming wedding even without Her Majesty's official consent.
As per Royal protocol, the queen has to approve marriages when it comes to members who are in line to the throne.
On March 14, 2018, the Queen has officially given the couple her blessing through a statement released by the Buckingham Palace.
'I declare My Consent to a Contract of Matrimony between My Most Dearly Beloved Grandson Prince Henry Charles Albert David of Wales and Rachel Meghan Markle, which Consent I am causing to be signified under the Great Seal and to be entered in the Books of the Privy Council,' the statement reads.
Prince William and Kate Middleton went through the same experience before they got married at Westminster Abbey in London on April 29, 2011.
The Duke and Duchess of Cambridge, who are already parents to two children - Prince George and Princess Charlotte, received their official consent one week before their wedding.
Meanwhile, Meghan will have a new title bestowed on her after her big day.
According to People, Meghan's title will be Her Royal Highness Princess Henry of Wales. But there's a possibility that she will become the Duchess of Sussex if the Queen decides to change Harry's title from His Royal Highness Prince Henry of Wales to the Duke of Sussex.
Sussex's Dukedom is available, so it's suspected that Harry and Meghan will become the Duke and Duchess of Sussex. The title of Duke of Sussex has been unassigned since 1843.
