Everything has looked pretty official so far (sure they even have their own merch that you can start stocking up on ahead of the celebrations) however the couple have only formally received consent from the groom's grandmother to become man and wife.
Not that it was even really in doubt.
In a letter to the Privy Council, the Queen of the United Kingdom gave her approval to the marriage of her 'dearly beloved grandson' Harry and the US actress Meghan Markle, using their names 'Prince Henry and Rachel'.
The letter, which is required for the approval of marriages of the first six people in the line of succession, read: '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.'
Eagle-eyed royal watchers expressed surprise at the formal wording of the wedding announcement when it was made after the couple announced their engagement in November last year, noting that the names Henry and Rachel were used, instead of the couple's more familiar names Harry and Meghan.
A similar letter of approval for the Duke and Duchess of Cambridge's marriage was made just one week before their 2011 wedding, so it seems things are moving along nicely and perhaps ahead of schedule for the royal wedding in May.
Meghan Markle, 36, is reportedly receiving etiquette lessons as part of her jam-packed schedule ahead of the big day, with Prince Charles' former butler, Grant Harrold revealing: "She has to be careful what she says, how she says it, and how it's taken because after the 19th of May, it will be a reflection of the royal family.
"It's everyday things - from the way she walks, the way she speaks, the things she does, how she eats, how she holds her cup, how she dresses - everything will be looked at. There will be a lot for her to adapt to."
Wedding plans are in full swing for the bride to be, who is reported to have spent a low key hen with a few very close pals in the Oxfordshire countryside over the weekend.
Meghan and her friends spent the day at the ultra plush private members' club the Soho Farmhouse for her ultra relaxing bridal shower, where the friends reportedly exchanged gifts and spent quality time together.
