Queen ElizabethandPrince Philipwere noticeably absent from Monday’s christening after the palace announced that the royal couple would not be in attendance. The decision, which was likely due to her busy schedule, was “mutually agreed” between the 92-year-old monarch and William and Kate “some time ago,” a palace source tells PEOPLE.
