Kate Middleton Baby - Ever since news widely circulated that British royals Prince William and Kate Middleton are having their second child, royal watchers have been very excited for the duchess' due date. Now, reports claim that the Duchess of Cambridge could give birth today or tomorrow.

While Duchess Kate's exact due date has not been made public, sources widely believed that the official due date is on April 25. However, Daily Mail reported the expected date could be wrong and Kate Middleton could give birth to the second royal baby as early as today or tomorrow.

Last month while speaking during an engagement in London, Kate Middleton revealed that her second baby will be due in mid to end April. And though April 25 is widely thought to be the Duchess of Cambridge's due date, sources close to the royal family emphasized that it has never been officially confirmed as such.

"We haven't ever confirmed a due date," a Kensington Palace source said. "The Duchess herself said mid to late April and there have been plenty of dates bandied around in the media but we've never confirmed anything and we never will."

Meanwhile, we previously reported that Prince William will take two weeks of paternity leave from his training for a new job as an air ambulance helicopter pilot, to help care for the second royal baby. On Wednesday, the Kensington Palace released a statement about the prince's training completion.

"The Duke of Cambridge has completed the first phase of his in-work air ambulance helicopter pilot training with Bond Air Services earlier than anticipated..." the statement read. "As he now will not have any further training to complete after returning from paternity leave, he will not return to duties with Bond until that time, and will remain on unpaid leave until then."

As the arrival of Prince William and Kate Middleton's second baby approaches, media frenzy will be expected. On April 16, The News revealed the media started a countdown and set up a press pen outside the hospital where the duchess is due to give birth. E! News also added parking in the area has been suspended until April 30 for the "special event."

In the meantime, Prince William and Kate Middleton are expected to welcome their second baby at a private section of St Mary's Hospital called Lindo Wing in Paddington, central London. And if the duchess will give birth to a princess, she could be worth $1.5 billion to her country.
