Here's your first look at Prince Louis' christening!

It's official!

Prince Louis has been christened and we've finally had our first look at the Duke and Duchess of Cambridge and their three children together as a family of five.

Yesterday members of the royal family - including the Prince of Wales and the Duchess of Cornwall, the Duke and Duchess of Sussex, and Michael and Pippa Middleton - gathered in a private ceremony at the Chapel Royal at St James’ Palace in London to watch the tot’s baptism.

Louis was baptised by the Archbishop of Canterbury, the Most Reverend Justin Welby in a 40 minute service which started at 4pm local time.

The royal newborn wore the same christening gown as his siblings, which is a replica of the robe made for Queen Victoria's eldest daughter in 1841, which is now too delicate to be worn.

The Duchess of Cambridge - who also has four-year-old Prince George and three-year-old Princess Charlotte with Prince William - was heard describing her son as "very relaxed and peaceful” and said she hopes "he stays like this.”

Ahead of the service it was revealed the 11-week-old baby has six godparents, who are all friends or family of the Cambridges.

The venue of the royal tot's christening, had a profound significance to Prince William, as his late mother, Princess Diana's coffin was placed at the palace's altar before her funeral at Westminster Abbey in 1997.
