It's a boy!

HRH the Prince of Cambridge was born safely today to first-time parents the Duke and Duchess of Cambridge at 4.24pm today, weighing in at a healthy 8lb 6oz.

'The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news,' read the official notice sent out by Kensington Palace this evening. Prince William was present at the birth.

The Duchess was admitted to the private Lindo Wing of St Mary's Hospital in London - where William was born in 1982 - in the early stages of labour at around 6am this morning. Thus followed a day of epic breath-holding worldwide, before the news of the new, as-yet unnamed Prince's birth broke just before 8.30pm tonight.

He is third in line to the British throne.

According to the iconic royal easel, upon which the formal birth notice has this evening been placed, 'Her Royal Highness and her child are both doing well.'

And, as congratulations flood in, it's the new father's that really put a lump in our throat.

Prince William said simply: 'We could not be happier.'
