And when it comes to picking her wedding dress, Meghan enlisted the help of her bestie/stylist Jessica Mulroney to help choose The One.
According to Good Morning America, Prince Harry's bride-to-be enjoyed a dress very successful session with Jessica at Kensington Palace recently.
They claim the Suits star flew out her BFF from Canada and put her up in the palace for four days as they worked through a treasure trove of options.
Royal reporter Omid Scobie told Good Morning America the 36-year-old has indeed found her wedding dress.
"Sources tell me that Meghan Markle has officially picked a wedding dress designer and had her first fitting at Kensington Palace last week," Omid also confirmed on Twitter.
"BFF and bridal expert Jessica Mulroney is guiding Meghan though the process and quietly flew in to London on Jan 10, spending four days at the couple's Nottingham Cottage home," he added.
"I'm told that they went through a number of options with the designer and Meghan was "incredibly excited" to see things start coming together."
"Jessica, who is an accomplished fashion advisor and bridal stylist, has helped piece together a number of Meghan's most recent looks (including her iconic engagement announcement outfit). She is also helping with several other wedding day elements," Omid explained.
However, Meghan's wedding dress designer will remain under lock and key for the time being.
"Right now only a small, select group of people know the designer's name, so don't expect to find out any time soon. Even Harry made himself scarce during the first fitting," Omid claimed.
While we wait for the big reveal, one thing we know for sure is that Meghan will be rocking a royal tiara!
"Catherine borrowed The Queen's Cartier Halo tiara in 2011 when she married William, so I imagine Meghan will also borrow one of The Queen's pieces," founder of the Australian School of Etiquette Zarife Hardy tells us.
As for the dress?
"It will definitely have a train, all royal brides have a train. I think it will be relatively fitted, probably with sleeves and it will be something very, very elegant because she'll be re-branding very quickly."
Meanwhile it's also believed Jessica's daughter Ivy will be joining pageboy Prince George and flower girl Princess Charlotte as another mini flower girl.
