Kate, the Duchess of Cambridge has gone into labour, with a new Royal baby now only hours away.
The 31-year-old was admitted to the private Lindo wing of St Mary’s Hospital in Paddington, London, on Monday morning.
The Royal couple have insisted throughout the pregnancy that they do not know the sex of the child, and have deliberately kept it a surprise.
The Duchess arrived at the hospital by car, and Prince William was at her side at the hospital, it was reported.

Bookmakers have had a field day cashing in on speculation of the baby's gender, possible names, and even hair colour.
William Hill has a girl at favourite at 4-7 with the top names Alexandra, Charlotte, Elizabeth, Diana and Victoria. They are taking odds of 5-4 for a boy with George and James favoured.
It is the same hospital where the baby’s father Prince William was born to Prince Charles and the late Princess Diana 31 years ago.
The birth will be officially announced via a proclamation signed by doctors on an easel at the gates of Buckingham Palace..
In June it was announced the Duchess was hoping to experience a natural birth, despite earlier revealing she was "nervous" about the delivery.
