LONDON (CBSDFW.COM) – Kensington Palace announced that Catherine, Duchess of Cambridge, or Kate, as she’s known to most of the world, gave birth to a baby boy this morning.

The third addition to Prince William and Kate’s family was born at St. Mary’s Hospital in London.

The Palace had said Kate arrived at the hospital in “the early stages of labor.” Royal officials confirmed that she had been taken by car to St. Mary’s and admitted to the Lindo Wing — the same place where she gave birth to Prince George and Princess Charlotte.

The baby boy is fifth in line to the British throne, after grandfather Prince Charles, father William, brother Prince George and sister Princess Charlotte. He is Queen Elizabeth II’s sixth grandchild.

After posing for photographs, William and Kate left the hospital later in the evening with new baby in tow, giving the world its first look at the new royal nestled into his car seat. Earlier in the day, William brought the baby’s siblings to St. Mary’s to meet their younger brother.
