Duchess Kate is reportedly four days overdue

Royal Baby fever (round 2!) is reaching an all-time high in London as the Duchess of Cambridge is reportedly four days overdue. With multiple outlets reporting that Thursday, April 23 was in fact Kate's due date, the next Prince or Princess is keeping us all waiting.

According to The Telegraph, senior officials in British Parliament were notified of an April 23rd due date by the Palace. As a result, Kate may be induced in the next week if she becomes uncomfortable. It's not likely that this is the case, however, since the Duchess has been out and about -- spotted at a petting zoo with George a little over a week ago, and even more recently at Zara in London. She seems pretty comfortable to us!

Prince George was also said to have arrived three days late when he was born in July of 2013. If George's little brother or sister waits just a couple more days (Wednesday April 29th), he or she will share a birthday with William and Kate's fourth wedding anniversary.

While fans and media alike wait for news, a satirical artist has made an appearance outside of the Lindo Wing on Monday to show off a painting he's made of Duchess Kate. In 2013, Kaya Mar's painting of Kate -- which portrayed her as the Virgin Mary -- was met with lots of criticism and called "creepy" and "bizarre." His latest painting shows a pregnant Kate (again as Mary) with Prince George at her side. While the press has been asked to steer clear of St. Mary's Hospital until Kate is officially in labor, some fans have been waiting outside for weeks already.

It's clear that everyone is a little overly excited to welcome the newest heir to the British throne, and we're sure William and Kate are ready, too! Click through above to see Kate's maternity style for her second pregnancy, and see Prince George's most adorable moments, below.
