WATCH: It's a boy!

Prince Harry says "over the moon" after the birth of his first child.

Buckingham Palace has confirmed that the Duchess of Sussex safely delivered a son at 5:26am London time, which is just before 12:30am, our time.

The baby weighs 7lbs 3oz, and The Palace says Harry was there for the birth.

Both mom and child are doing well.

We don't know the name of the child though, with the Palace saying a name will be announced in due course.

The baby is seventh in the line of Succession after His Royal Highness The Prince of Wales, His Royal Highness The Duke of Cambridge, His Royal Highness Prince George of Cambridge, Her Royal Highness Princess Charlotte of Cambridge and His Royal Highness Prince Louis of Cambridge.
