Prince Harry, 34, and Meghan Markle, 37, first met in the summer of 2016 after being set up on a blind date.
Within two years, the pair were married after tying the knot earlier this year at Windsor Castle.
While they were dating, the couple made sure to see each other between Toronto, where Meghan was filming TV show Suits, and London, where Harry lives.
The royal protected his girlfriend from the paparazzi when travelling with a very sweet gesture.
Harry made sure she was able to get through London Heathrow Airport using private access to avoid people spotting her.
This is because the actress would regularly come through Terminal 2, where Air Canada lands, and be spotted by other travellers and photographers as their relationship hit the headlines.
A source previously told Express.co.uk: “All the necessary security checks must be carried out in advance or onboard because she walks straight from the plane steps to Harry’s car.”
Meghan also did her bit to make sure the process was as smooth as possible.
The Duchess “only carrie[d] hand luggage” according to the source so she would not have to wait for her checked suitcase at baggage claim.
It was also rumoured that she would use the Windsor Suite, one of the most expensive VIP lounges in the world, however, it seemed that Harry decided to protect her in his own way.
Kensington Palace did not comment on the claims at the time, while a Heathrow spokesman said it would be “inappropriate” to discuss confidential matters in regards to travelling members of the Royal Family.
While dating, Prince Harry also broke royal protocol in a bid to see his girlfriend while she was across the pond.
The prince returned from a work trip to the Caribbean and instead of heading back to the UK, changed his plans to travel to Toronto instead.
This is frowned upon by the royal family, as “working visits should not be combined with personal travel”.
Harry and Meghan also went on a secret trip earlier this year to Amsterdam.
The couple joined other celebrities for the launch of Soho House Amsterdam in the famous city.
Meghan is known to be a fan of Soho House, having attended the Istanbul launch in 2015 and also rumoured to have had her hen do at Soho House in Oxfordshire.
However, there was an awkward run-in between Prince Harry and one of his rumoured ex-girlfriends.
Jenna Coleman was connected to the royal before he met Meghan, with the pair both being spotted at breakfast during the stay.
