All the sweet details from Prince George's christening

It's the big day! Kate Middleton and Prince William are celebrating Prince George's christening. Led by the Archbishop of Canterbury Justin Welby, the 35-minute, private ceremony was at 3pm London time at the Chapel Royal in St. James's Palace.

We wish we could be a fly on the palace wall for the happy occasion but since only about 50 guests are attending, here are all the photos, plus eight key things to know about the baptism of Prince George.

1. Prince Harry and Pippa are not the godparents. Seven godparents have been chosen and the list is comprised of good friends of the couple as well as one royal, William’s cousin Zara Tindall. Aunt Pippa and Prince Harry did, however, both have readings in the service, according to a release from The Prince of Wales' official site.

2. There will be professional photos. No casual snaps from Kate’s dad this time around. Will and Kate have hired photographer Jason Bell to capture this historic event. His photos of George will be released tomorrow.

3. The prince wore the lacy, ornate (and long!) Royal Christening Robe that’s an exact replica of the one used for Queen Victoria's daughter in 1841.

4. The midwives got an invite. To show their appreciation for a smooth delivery, the royal couple reportedly included the team of midwives from St. Mary’s Hospital, according to US Weekly. Let’s hope it’s not a busy day in the maternity ward!

5. They served wedding cake. After the service, there will be a private tea at Clarence House, where guests will have "christening cake," a tier taken from the couple's wedding cake.

6. Prince George was royally well-behaved. The baby "gurgled happily" when his great grandparents The Queen and the Duke of Edinburgh entered, he was described as having a "commanding manner" by the Dean of the Chapel Royal (where the service was held) and was "wide-eyed" at the end of the 35-minute service, according to a report from The Duke and Duchess of Cambridge's official site. (You would be too if you had water from the River Jordan splashed on your head!)

7. Kate wore an Alexander McQueen outfit and nude-and-ivory Jane Taylor hat.

8. The christening featured Prince Harry and Pippa Middleton reading the two lessons, from Luke ch. 18, verses 15-17, read by Pippa, and St. John ch. 15, verses 1-5, by Prince Harry. According to a statement by the palace: "The Duke and Duchess of Cambridge have chosen two hymns, two anthems and two lessons for the service." The hymns are "Breathe on Me, Breath of God" and "Be Thou My Vision."  The anthems were "Blessed Jesu! Here we Stand," which Richard Popplewell wrote for William's Aug. 4, 1982, baptism, and John Rutter's "The Lord Bless You and Keep You", which were  performed by the Choir of Her Majesty's Chapel Royal and 10 Children of the Chapel Royal. The Processional Organ Music was J. S. Bach’s Fantasia in G (BWV 572), and the Recessional Organ Music C. M. Widor's Toccata from Symphony No 5.
