The royal baby has arrived! Britain’s Duke and Duchess of Cambridge, Kate Middleton and Prince William, welcomed their second child, a girl, on Saturday. The child joins the couple’s 1-year-old son, HRH Prince George.

Kate had arrived at St. Mary’s Hospital in Paddington early on Saturday to give birth. 

Kate and William announced they were expecting in October following several rumors Kate, now 33, was with child. The palace confirmed that the Duchess was due to welcome her baby in April. The Duchess later shared more specific details about her due date, revealing she would deliver in mid-to-late April during an appearance at London’s Brookhill Children’s Center in March, one of her last appearances before starting maternity leave. 

The couple’s child is now fourth in line to the British throne, one spot ahead of William’s brother, Prince Harry. William’s father, Prince Charles of Wales, is currently next in line behind the reigning Queen Elizabeth II. Kate and William’s first-born son, Prince George, is third in line to the throne.
