Smith, who portrays Prince Philip in Netflix series "The Crown", struggles with the same transition Markle is about to confront and later has difficulty adjusting to life in the shadow of his wife, Queen Elizabeth II, played by Claire Foy.
Apparently, Pornhub visitors also showed a little spike of interest in Ms. Markle when her and Harry first went public in November of previous year - with searches increasing by 1430 per cent.
"You realise the fact that Elizabeth forbade her sister from marrying a divorced man; it goes to show how time has changed and how they've had to evolve", said Foy, alluding to Markle's divorce from Trevor Engelson in 2013. And they really have.
"It's such a tradition in her life, and it's such a huge thing to take on". This would not have been conceivable, this would not have happened 50 years ago.
Meanwhile, Markle is completely aware of what she's signed up for since she and Prince Harry started dating.
Meghan, who last week confirmed she is engaged to Prince Harry, will give up her acting career as she embarks on her new role as a royal.
Sounds like the status quo of most A-list actors/singers/athletes, and the "Suits" actress probably knows exactly what she's signing up for.
A famous quote reads - "Brothers are as close as hands and feet" - and it seems like Prince Harry believes in it in real life too.
"As a lifelong fruits and vegetables ambassador and a United Kingdom resident, designing a banana cake worthy of Prince Henry of Wales and the future Duchess Meghan Markle represents a higher calling, both personally and professionally", said Allison.
"At the moment for us it's going to be making sure that our relationship is put first, but both of us have passions for wanting to make change for good", said Prince Harry.
