The Duchess of Cambridge entered a London hospital Monday in labor with what will be the third child for her and husband Prince William, Britain's Kensington Palace said.
The 36-year-old duchess traveled by car to the private Lindo Wing of St. Mary's Hospital in central London. The palace said she was in "the early stages of labor."
William and Kate married in 2011 and have two other children: Prince George, 4, and Princess Charlotte, who turns 3 next month. Both were born at the same hospital, as were William and his younger brother Prince Harry.
The baby, whose gender has not been announced, will be Queen Elizabeth II's sixth great-grandchild and fifth in line to the throne, after grandfather Prince Charles, father Prince William and the two older siblings.
