Prince William hints that Kate's due date might be sooner than we think

Is THIS when we'll have a new royal baby?

Prince William has hinted that his wife Kate's due date might be sooner than initially predicted during a recent appearance in London.

It was only a few weeks ago that it was announced that a new royal baby was on the way, just before little Prince George started his first day at school.

While it was initially thought that Kate would be giving birth sometime in March, Prince William has now implied that the arrival of the couple's third child couple come around even sooner.

At an official appearance in East London yesterday, while visiting a charity called Spitalfields Crypt Trust, the dad was congratulated on his wife's pregnancy by a trainee midwife, to which he replied: 'All the best with the midwifery. I may see you sooner than you think.'

It was previously thought William gave away the due date of the new royal baby soon after the big reveal, when he attended an event in Oxford.

Speaking with an audience member at the National Mental Health and Policing conference William said after being congratulated on the bundle of joy he has on the way: 'Thank you, it's very good news. There's not much sleep going on at the moment!'

'It was a bit anxious to start with, but [we can] start celebrating this week', he added.

Has William revealed his wife's due date?

As expectant parents usually wait until the 12 week mark to celebrate and share the news officially with friends and family, it was thought that his comments could mean Kate was three months pregnant at that time, which would put the royal due date sometime around March 2018.

Kensington Palace also announced yesterday Kate will be attending her first royal engagement since confirming her pregnancy, an event which will take place on Tuesday 10th October.

The Duchess of Cambridge will attend a reception at Buckingham Palace on World Mental Health Day, alongside Princes William and Harry, where the trio will 'celebrate the contribution of those working in the mental health sector across the UK'.

George and Charlotte will have a new sibling in just a few months

The expectant mum has been suffering from Hyperemesis Gravidarum, which means she's experienced severe nausea and vomiting during the first trimester of the pregnancy.

The condition has forced her to miss her son's first day of school, so the fact that she will be attending a royal event very soon could indicate that she is feeling better and at least three months pregnant now - but we'll have to wait to find out...
