George and Charlotte have arrived to meet their new baby brother

Charlotte is just too cute.

Earlier today, the Duke and Duchess of Cambridge have welcomed their third child. It was announced on Monday that Duchess Kate had given birth to a baby boy. Kensington Palace shared a sweet announcement on behalf of the couple, which said:

"Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 1101hrs. "The baby weighs 8lbs 7oz. The Duke of Cambridge was present for the birth. "Her Royal Highness and her child are both doing well."

And now, George and Charlotte have arrived at the hospital to meet their new baby brother.

The whole family seem to be delighted for Kate and William as the Queen later made a statement.

"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."

We're all looking forward to seeing Kate and the new baby for the first time later.
