But while the world looks on, getting carried away with all the glorious PDA between the pair and anticipating an engagement announcement any day now, there's actually a lot more to a big decision like that than we'd like to think.
Prior to marrying Prince William, Kate Middleton had worked as an accessories buyer for retailer Jigsaw and then as a project manager for her family's event planning business.
According to The Daily Star, the 36-year-old will film her final scenes for the show next month as she prepares for more public appearances with Harry and become a "full-time royal".
"Meghan knows she can't really act at the same time as being a princess and is happy to make this career sacrifice", a source told the paper, adding that she'll instead focus on her charity commitments with Unicef.
He allegedly gave her a custom ring that he designed. What began as a passion project (my little engine that could) evolved into an fantastic community of inspiration, support, fun and frivolity. Did you see it coming?
During Meghan's recent visit to London she was spotted being chauffeured around England's capital in a black Volkswagen vehicle, which has set tongues wagging she is engaged to Harry, especially because the Duchess of Cambridge was driven around in a dark Audi A3 prior to her official engagement announcement. "But I'm sure she's got plenty of people on her list". Will they tie the knot before Christmas?
"So, she'll have to move eventually if they want to be together", another source told the Sun. After that, the couple will likely have a low-key spring wedding.
