A new portrait of the Duchess of Cambridge holding Prince Louis after his christening was released by Kensington Palace.
Prince Louis slept through the entire ceremony but was pictured alert and with a wide opened-mouth smile as he was held upright by his mother in the gardens of Clarence House.
Clicked by Matt Porteous, the picture was released on social media nearly 12 hours after Kensington Palace put out another four shots by Matt Holyoak from the day last night.
The palace tweeted, 'The Duke and Duchess hope that everyone enjoys this lovely photograph of Prince Louis as much as they do.'
Louis was wearing a replica of the royal christening robe, made of fine Honiton lace lined with white satin, which was created in 1841 for Queen Victoria's eldest daughter, Victoria, the Princess Royal.
That gown was worn for all subsequent royal baptisms including the present Queen, her children and grandchildren.
However, by 2008 it was clear the gown was becoming delicate and the Queen's senior dresser Angela Kelly ran up a hand-made replica in order to preserve the original.
Kate wore a cream Alexander McQueen dress with floral headpiece by Jane Taylor, and her long hair was swept back in a bun.
