Prince Harry and Meghan Markle will no doubt be looking back with happy memories today.
That's because it marks five years since they tied the knot in their fairytale wedding at Windsor Castle.
But it's not just the Sussexes who may decide to take a trip down memory lane by looking at some of the stunning photos taken on their big day.
Fans also still like to look over the beautiful pictures and footage that were captured on the memorable day in 2018.
And it seems some have spotted a secret message hidden on the couple's wedding car, which they used to drive to their evening reception.
Following the ceremony, Harry and Meghan made an outfit change and set off from Windsor Castle to Frogmore House in a blue Concept Zero E-type Jaguar, with Harry at the wheel.
The sports car was originally manufactured in 1968 but has since been converted to electric power.
In a fleeting moment, footage shows that the car registration plate on the vehicle read E190518.
It is believed the E stands for established, with the other numbers being the date of their wedding 19/05/18.
Taking to Twitter, one fan wrote: "Yoooo I am so embarrassed. I was watching the royal wedding for the 200th time and it’s only now that I noticed the licence plate."
While another said: "Wow! Hadn’t noticed. Thanks."
And one added: "Oh wow I never noticed that, good job."
Meanwhile, in the fourth episode of the couple's six-part Netflix series, Harry & Meghan, viewers get the chance to see a number of amazing unseen pics from the wedding party.
The Sussexes laughed about having to use a sword to cut their wedding cake, with Meghan saying: "It was great. It was all so over the top.
"Most people were like, 'What is happening? Elton John is performing?' I couldn't find my mum. She'd made a beeline for the stage to watch Elton sing."
There are snaps of Rocketman singer Elton performing on the piano and Harry having a laugh with Hollywood star Idris Elba, who did a DJ set.
Then everyone gathered outside to watch the incredible fireworks that were on display.
It's unknown how Harry and Meghan will exactly be celebrating their fifth wedding anniversary today.
The traditional gift to give for five years of marriage is wood, so it's a possibility that the couple will exchange gifts made from the material.
It is also likely they will be marking the day privately, probably with their children Prince Archie and Princess Lilibet.
