Prince Louis was carried into the chapel by his beaming mother, wearing the handmade replica of the Royal Christening Robe, which in 2008 replaced the original which had been worn for all royal christenings since that of Queen Victoria's eldest daughter in 1841.
The trio enjoyed the yearly show and fans loved that the young royals wore matching plimsolls, which retail at £35.
Meade is the wife of James Meade, who is not only another Eton friend of William's, but is also the godfather to Princess Charlotte, according to the Daily Mail.
Middleton, who is now five-months pregnant with her first child with husband James Matthews, hid her baby bump under the long-sleeved pleated gown.

Prince Louis' christening was the first time that the Duke and Duchess of Cambridge made a public appearance with all of their children.
