One of the most monumental days of Prince George‘s young life has arrived, and is letting you experience it live.

Starting at 8:30 a.m. EST, we’ll be streaming the prince’s christening ceremony, beginning with the arrival of friends – who are mostly coming from Kensington Palace to St. James’s Palace – followed by immediate and extended family.

The Archbishop of Canterbury will conduct the service, which will be attended by the Queen and her husband, Prince Philip, Prince Charles and his wife Camilla, Prince Harry and the Duchess of Cambridge‘s family, the Middletons.

One person who will not be in tow is Harry’s girlfriend Cressida Bonas. As a source explained to PEOPLE on Tuesday, “If she went to this totally private service, it would be tantamount to saying they were about to be engaged.”
