Next month, Prince William and Kate will celebrate 11 happy years of marriage and during that time they've welcomed three children into the world.
The Duke and Duchess of Cambridge seem happier than ever as they carry out their royal duties in Belize, but it hasn't always been easy - especially in the early days of their relationship.
In fact, the couple actually parted ways, for around 10 weeks in 2007, before reconciling and later becoming engaged in 2010.
The decision to part is reported to have been William's, with one of Kate's former colleagues claiming they saw her take a phone call from her now-husband in which he ended their relationship.
"Around the middle of the day, she was pacing the car park outside the office on her mobile," the colleague told the Mirror back in 2007.
"A few people noticed because it's a pretty unusual thing to do. She'd deliberately gone outside to take the call because she didn't want to be overheard.
"Kate was walking up and down and looking upset as if she was having an argument. But she didn't cry. Word went round that it was William and they were having problems. Now it's clear what it was all about.
"When she came back to the office she didn't say a thing and disappeared for the rest of the day. We didn't think anything about it at the time. But looking back, the call was definitely a girlfriend-boyfriend tiff."
The break didn't last long, with royal author Robert Lacey claiming William found it surprisingly difficult to date, and later coming to the realisation he missed Kate and her family.
Both William and Kate have acknowledged the split publicly, the Wills insisting they were both "trying to find their own way," at the time.
"It was just a bit of space. It worked out for the better," he said, and despite the fact Kate admitted she "wasn't very happy" about the split at the time, she has since come to the realisation it was for the best - and actually made her stronger.
Kate said: "At the time I wasn't very happy about it but actually it made me a stronger person. You find out things about yourself that maybe you hadn't realised.
"I think you can get quite consumed by a relationship when you're younger. I really valued that time, for me as well, although i didn't think it at the time."
