The duchess's due date has not been officially announced
The Duchess of Cambridge
is in labour, as the world's media gathers outside the hospital awaiting
news of the latest addition to the Royal family.
Catherine and the Duke of Cambridge arrived by car at St Mary's Hospital in Paddington, west London, at 06:00 BST.
Kensington Palace said she was in the early stages of labour, which was progressing as normal.
The couple do not know the sex of their first child, who will be third in line to the throne.

Royal vehicles were seen at a back entrance to the hospital
at about 06:00 BST, with the announcement coming from Kensington Palace
90 minutes later.
