From stealing mum, Kate’s sunglasses, to blowing cousin Archie and his Aunty Meghan a kiss, to adorably sucking his thumb, the sixth in line to the throne was really just too cute for words.
But this isn’t the first time the royal cutie has grabbed out attention.
Last month the public let out a collective ‘Ahhh’ as Louis sweetly waved from the balcony of Buckingham Palace during Trooping the Colour.
And this adorable picture of Kate and Prince William’s youngest toddling through the Duchess of Cambridge’s Back to Nature garden at the Chelsea Flower Show is just too cute for words.
And who could forget the moment the little prince playfully made a grab for Prince Charles during his 70th birthday photoshoot.
Don’t tell Archie, but Prince Louis is secretly our favourite. (for now!)
