Pippa Middleton has given birth to a baby boy.
The baby was born on Monday, weighing 8lb 9oz (3.8kg), a spokeswoman for Pippa and her husband James Matthews said.
The baby was born on the day the palace announced that Prince Harry and his wife Meghan, the Duchess of Sussex, are expecting their first child.
Kensington Palace says that Prince William and Kate are "thrilled for Pippa and James".
The new baby will be a cousin to William and Kate's three children - George, 5, Charlotte, 3, and five-month-old Louis.
