The Duchess of Cambridge popped into Buckingham Palace for the second day in a row, suggesting that her baby isn't about to make an imminent appearance, Mail Online can reveal.
The royal mother-to-be, who is at least four days overdue with her second child, was seen driving herself into the Queen's London residence, sources revealed.
It is not clear whether her son, Prince George, was with her, but it is believed that her husband, Prince William was. The pair later returned to Kensington Palace together.
A spokesman for the couple, who do not know the sex of their new baby, declined to comment on why the couple spent the morning at the palace. The Queen was not in residence as she is holding court at Windsor.
If the little prince or princess, who will be fourth in line to the throne, is born later today it will be a double celebration for William and Kate who are also celebrating their fourth wedding anniversary.

But the fact that the Duchess is still out and about suggests that the new fourth in line to the throne is not in a hurry.
The fact that the Duchess is continuing to go about her day to day routine at such a late stage in her pregnancy will add to speculation that she is likely to be induced.
Although some women are allowed to go on for more than two weeks after their due date, medical experts have suggested that her consultants - led by Surgeon/Gynecologist to the Royal Household Guy Thorpe-Beeston - are probably keen not to want the Queen in waiting to go over by much more than a week.
Kensington Palace officials are not taking any chances, however, and this morning Westminster City Council lengthened the suspension of parking restrictions outside the private Lindo Wing at St Mary's Hospital, Paddington, where Kate is due to give birth, for another five days.
The extension to the restrictions, which had begun on April 15 and had been due to run out tomorrow, now runs well into May - even closer to the General Election of May 8. That said, palace officials have always made clear they think a clash would be extremely unlikely.
Sources have told the Mail that the Duchess's due date was on 25th April and Kate herself told well-wishers the baby was due "mid to late April".
A spokesman for the council said: "The parking restrictions will be extended at the moment for the next five days until May 5. If there is still no news by then it will be extended again.
"The signs will be amended possibly today, if not tomorrow morning."
As revealed by the Mail last year, Kate is a frequent visitor to Buckingham Palace's covered pool, used by members of the royal family and staff, where she is teaching George to swim.
Yesterday she appeared distinctly unconcerned by the fact that she is now several days overdue, manoeuvring her car carefully past a ten-deep crowd waiting at the gates of the Queen's official residence for the daily changing of the guard.
Some even cheered when they saw the Range Rover going through and onto the palace forecourt - although it is not clear whether the tourists had actually spotted her inside.
The Queen was not present at the time as she is still resident at Windsor Castle.
Aside from the severe ante-natal sickness that dogged its first few weeks, Kate, 33, has enjoyed a remarkably healthy pregnancy - eating well and exercising regularly.
