We look back on 2010 with a lot of fondness and nostalgia because that was the year when the fairytale of the century came to official fruition: Kate Middleton and Prince William got engaged!

We still remember every detail about the beautiful engagement photos which were shot by famed fashion photographer, Mario Testino; from Kate's pretty white Reiss dress and Will's smart suit to the second photo which had the royal couple dress in more casual garb (and hugging!).

Testino recently chatted with The Telegraph about what went on behind-the-scenes during the famous photo shoot and describes meeting the Duchess of Cambridge for the first time in 2008 and says he knew immediately that Prince William was "in love with Kate. I knew they would stay together."

Just two years later the Peruvian-born photographer got the chance of a lifetime to photograph the couple and the results were nothing short of spectacular.

"I waited a long time, an hour or two, to make that picture perfect," said Testino. "But I wasn't totally satisfied. Then, when I'd finished the shoot, they were about to leave and they suddenly hugged in front of a radiator. I took my camera and that was the picture that ran everywhere - it was spontaneous emotion… you could see they were completely in love."

It's not that surprising that Testino shot the future King and Queen of England; after all, Anna Wintour's bestie has a longstanding relationship with the royal family and shot the late Princess Diana several times for magazines.

But the photographer said Prince William's mum doesn't remind him of Catherine.

"Kate, she is beautiful in a different way: she radiates happiness," he told The Telegraph. "She is comfortable in her love." Awww!
