Prince William’s Wife, the Duchess of Cambridge has given birth to her third child, a boy on Monday morning.
The Kensington Palace says the child was born at 11:01 a.m. (1001 GMT; 6:01 a.m. EDT), a few hours after Kate was admitted to London’s St. Mary’s Hospital in labor.
Prince William was present for the birth of his son, who is fifth in line to the throne.
The palace says “the queen, The Duke of Edinburgh, the Prince of Wales, the Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news.”
The couple, who married in 2011, has two other children: Prince George, 4, and two-year-old Princess Charlotte. Both were born at the same hospital, as were William and his younger brother Harry.
British Prime Minister Theresa May has offered “warmest congratulations” to Prince William and the Duchess of Cambridge on the birth of their new son.
May says that “I wish them great happiness for the future.”
The Duchess of Cambridge and Prince William have since left the hospital and headed home with their newborn son.
The duchess, who gave birth about seven hours ago, emerged from St. Mary’s Hospital alongside her husband, holding the baby wrapped in a white blanket. The trio posed for photographers before going back inside.
The royals emerged a few minutes later with their infant in a carrier and got into a waiting car.
The newborn prince’s elder siblings, Prince George and Princess Charlotte, already had gone home after a brief first meeting with their baby brother.
Royal officials say the baby weighed in at 8 pounds, 7 ounces (3.8 kilograms). The prince, whose name has not been released, is fifth in line to the British throne.
