Queen Elizabeth arrived at Buckingham Palace in an SUV on Monday, while Kate is in labor at St. Mary's Hospital.
Last week, the 87-year-old monarch – who will be the baby's great grandmother – told children in Cumbria in northern England that while she didn't have a preference for a boy or a girl, she "would very much like it to arrive. I'm going on holiday. No sign yet."
The Duchess of Cambridge was admitted to the hospital in the Paddington area of London just before 6 a.m.
At the time, the Palace released a statement saying, "Her Royal Highness The Duchess of Cambridge has been admitted this morning to St. Mary's Hospital, Paddington, London in the early stages of labour." Adding that "The Duchess traveled by car from Kensington Palace to the Lindo Wing at St. Mary's Hospital with The Duke of Cambridge."
The palace has added her labor is progressing normally.
Amid the excitement in the delivery room, Queen Elizabeth, Prince Charles and the Middletons will be told the news first. Though a royal source thinks it's "unlikely" that the Queen will visit the couple and their child in hospital. The assumption then is that they will take the baby to her.
