(Yahoo!) - Oh, baby! Exactly three months and one day after his birthPrince George has hit another milestone moment: He's been christened.

In a break from tradition, Prince William and Kate Middletonopted for a small, intimate ceremony attended by only their nearest and dearest. Guests gathered at 2:30 p.m. local time at the Chapel Royal at St. James's Palace in London to witness the happy occasion.

In attendance from William's side of the family tree were baby George's great-grandparents Queen Elizabeth II andPrince Philip, as well as Prince Charles and Camilla, and Prince Harry. Catherine's parents, Carole and Michael Middleton, along with her siblings, James and Pippa, were also present. It's interesting to note, however, that not one of these blood relatives was asked to be a godparent to the future king.

But that doesn't mean George will be on his own — because his parents did ask seven other people to accept the honors. Topping the list are two friends from school: Mr. Oliver Baker, who attended the University of St Andrews with both William and Kate, and Mrs. Emilia Jardine-Paterson, who went to Marlborough College with the duchess. Also included are Earl Grosvenor, the son of the Duke of Westminster; Mr. Jamie Lowther-Pinkerton, who served as Private Secretary to William, Kate, and Harry from 2005-2012; Julia Samuel, who was a close friend of Princess Diana; Zara Tindall, William's cousin; and Mr. William van Cutsem, a friend William has known since childhood.

Conducted by the Archbishop of Canterbury, the Most Reverend Justin Welby, the 45-minute service included two hymns, two lessons, and two anthems, one of which was "Blessed Jesu! Here We Stand," which was originally written for Prince William's baptism in 1982.

Clad in a handmade lace and white satin gown that is an exact replica of the robe made in 1841 for the christening of Queen Victoria's first daughter, there's no doubt Baby George looked his best. (The replica was first used in 2008 in order to preserve the 170-year-old original, just FYI.) The actual baptism took place in the same silver font that has been used for every royal christening since 1841, and was filled with water from the River Jordan.

Around 3:30 p.m. guests could be seen leaving the chapel. The women wore traditional hats and fascinators, and Kate stunned in a cream-colored ensemble. On their way out, Pippa and Carole stopped to shake the Rev. Welby's hand and (it seemed) thank him for a job well done. No one seemed more delighted than William and Kate, however, who were the picture of proud parents as they held their little prince in their arms.

Following the ceremony, Prince Charles and Camilla hosted a private tea at Clarence House where guests enjoyed slices of christening cake (yes, that's a thing), which is a tier that was saved from William and Kate's 2011 wedding cake. In other words, it was exactly as we expected — completely perfect.
