Prince Louis' As-Yet-Unseen Christening Pic Will Make You Smile As Big As The Little Prince Himself

Is he the cutest British royal baby of all time?

Just when you thought you could finally have a cuppa and a sit down after swooning over the three bonkers-level adorable official snaps from little Prince Louis' christening, BOOM! the royal family drop this bombshell of cuteness.

What you're gawping over right here is a fourth as-yet-unseen pic taken on the two-month-old royal's big day, and isn't it a corker?

This little treasure, featuring a super-smiley Louis in the arms of his elegant and doting mama Kate comes about 12 hours after three official snaps by photographer Matt Porteous were released on the Kensington Palace Instagram account.

Unlike the trio of more formal, posed shots that featured various members of the royal family -- including Louis' aunt and uncle the Duke and Duchess of Sussex, and grandparents Prince Charles and Camilla, Duchess of Cornwall -- this relaxed, candid snap features just the (mini) man-of-the-hour and his mum.

It's such an intimate pic -- taken close-up over Kate's Alexander McQueen-clad shoulder -- that it seems almost like an outtake, which makes it all the more special and exciting that proud parents, the Duke and Duchess of Cambridge, have kindly shared it with the world.

People are understandably going ga-ga on Twitter, and TBH who can blame them? He's a doll. Look out George and Charlotte, as some are calling Louis the cutest British royal of all time...
