What will Meghan Markle be learning in her six months of Princess lessons?

Watch your back Mia Thermopolis.

Meghan Markle has fitted seamlessly into the royal family from the moment she started dating Harry, from bonding with the Queen's corgis to getting an early invite to spend Christmas at Sandringham with the Windsors.

And now that the couple have tied the knot, Meghan is officially a royal, with the Queen giving Prince Harry and Meghan Markle the titles, Duke and Duchess of Sussex, as a wedding present.

The newlyweds made their first public appearance as Duke and Duchess at Prince Charles' 70th birthday party at Buckingham Palace this week, with Meghan nailing Duchess chic in a Goat dress and Philip Treacy hat.

But while she is proving herself to be in the know on royal protocol, wearing tights to public engagements and curtsying to both the Duchess of Cambridge and Queen Elizabeth on the regular, it has been revealed that Meghan will be undertaking Princess lessons.

Yes, really. The former Suits actress is set to attend six months of princess lessons to perfect her approach to the role - everything from lessons about Ascot to banquet etiquette. and while unlike Mia Thermopolis, she won't have Julie Andrews to turn to, one of her royal aides is set to stand in and teach her all things royal.

But what will she study?

'In terms of etiquette, there may be some advice on "British" traditions such as tea parties and formal banquets,' The English Manner Chief Executive Alexandra Messervy explained to InStyle of Meghan's princess lessons. 'There will be discussions on Royal Ascot and key events in the royal year, public outings, garden parties - which she did yesterday with aplomb grace and looked super—and I don’t think much else. Her Royal Highness has already shown she has film star poise and grace.'

Happy studying, Meghan.
