Kate Middleton catching Prince William laughing in church is the funniest thing you'll see today

We love them even more.

The Duke and Duchess of Cambridge are one of the most talked about couples on the planet.

But despite their royal status and influence (Kate Middleton effect, anyone?), they are refreshingly normal.

From using a lot of emojis on their official Instagram account to not being afraid to rip up the royal rulebook, these two never fail to make the public smile.

This was no exception yesterday, when a hilarious video of the couple went viral, while the Duke and Duchess were attending the Royal Air Force centenary at Westminster Abbey.

Kate wasn't expected at the service, breaking her maternity leave to be there, but it's a good thing she did, as she needed to be on hand to stop husband, Prince William, from giggling just before the service commenced.

The 36-year-old prince is seen to be trying to conceal a laugh, before being caught by his wife and explaining what was making him giggle.

Unlike Prince Harry and Meghan Markle, the Duke and Duchess of Cambridge rarely engage in public displays of affection, which has made this candid video all the more popular.

These two!
