The First Photos of Princess Charlotte at Her Christening Are Here! Plus, All the Details

It's a big day for the royal family, as those closest to the Duke and Duchess of Cambridge gather for Princess Charlotte's christening. Before the family of four even arrived at St. Mary Magdalene Church, a Kensington Palace spokesperson has announced intimate details about the baptism, including the reveal of Charlotte's five godparents. As soon as the official pictures come in from photographer Mario Testino, we'll post them here!

Update: Here's Kate, William, George (and Charlotte in the pram) making their way to the church! Kate is in Alexander McQueen and a Jane Taylor hat. George is also in an outfit similar to the one his dad wore 30 years ago to meet Prince Harry!

Curious George indeed! How adorable is the little prince on his tippy-toes taking a peek at his little sister?

Look at those eyelashes!

Details of the Service: Via Kensington Palace, the Duke and Duchess of Cambridge have chosen two hymns, one lesson, and two anthems for the christening of their daughter, Princess Charlotte. The hymns are "Praise to the Lord," "The Almighty," and "Come Down, O Love Divine." The lesson is from Matthew 18, verses 1-5, read by Mr. James Meade. The anthems are "I Will Sing With the Spirit" and "God Be in My Head," both by John Rutter. Members of the Sandringham Church Choir are singing at the service. The processional organ music is R. Vaughan Williams' Prelude on "Rhosymedre." The recessional organ music is G. F. Handel's Overture and Allegro from Concerto VIII in A.

The Archbishop of Canterbury, the Most Reverend Justin Welby, is baptizing Princess Charlotte. He is being supported by the Reverend Canon Jonathan Riviere, the rector of the Sandringham group of parishes.

Charlotte's Godparents: No members of the royal family were asked to be Charlotte's godparents. Although that was a surprise to many, the Duke and Duchess did pay tribute to Princess Diana by choosing William's first cousin, the Hon. Laura Fellowes, who is Princess Diana's niece. Additional godparents include Miss Sophie Carter (a close friend of Kate's, and according The Telegraph in London, the ex-girlfriend of Thomas van Straubenzee —also chosen to be a godparent), Mr. James Meade (a schoolmate of William's at Eton and one of his closest friends. He is married to Lady Laura Marsham), Mr. Adam Middleton (33 years old and Kate's first cousin; he's Michael Middleton's nephew and works for the Mayfair firm Manchester Square Partners. He recently got married to interior designer Rebecca Poynton), and Mr. Thomas van Straubenzee (one of Princes William's oldest school friends, who is married to the Duke of Northumberland's daughter Melissa Percy). Also of note from The Telegraph: Princess Diana was a close friend of the Van Straubenzee family and even was a nanny to Thomas' cousin before marrying Prince Charles.

The Tower of London Jewels: The jewels from the Tower of London rarely leave their home base, but of course today is no ordinary day. Princess Charlotte will be baptized at the baptismal font known as the Lily font, which was was commissioned by Queen Victoria and Prince Albert in 1840, for the birth of their first child, Victoria, Princess Royal. The flute bowl is decorated around the edge with spays of ivy and lilies, considered to represent purity, and water lilies were associated with new life. Water from the river Jordan will be used during the baptism.

Tea Time: Following the service, the Duke and Duchess of Cambridge will give a tea at Sandringham House. Guests will be served slices of christening cake, which is a tier taken from the Duke and Duchess of Cambridge's wedding cake.

Royal Congrats: The Prime Minister of Great Britain, David Cameron, has already tweeted his congrats this morning (alas, he will not be at the baptism).

Sights and Sounds: The weather has turned a bit dreary in Norfolk, where the Sandringham estate is located, but that hasn't stopped fans from gathering, including "royal fan" Terry Hutt.

Update: The weather is clearing up (thank goodness!), and the umbrellas have been put away. The guests will be arriving soon, with the royal family scheduled to appear by 11:30 A.M. ET.
