This is an old picture of Anita from earlier this year (pre-wedding) attending one of the celebrations right before Queensday.
Anita was certainly not pregnant then as she walked down the aisle four months later looking very slim.
As someone else commented in another Dutch thread, let's not engage in this endless speculation of Anita/Aimee is pregnant. Don't get me wrong, I love the Dutch royal family, particularly the van Vollenhoven family and it will be wonderful news when it is announced that Anita and Aimee are pregnant but let's wait for that moment so that we can enjoy it when it comes. It's rather anti-climatic to speculate about it for months and months and when it's announce it's rather disappointing as we've been speculating about it for months now.
Let's keep the focus on present-day activities by the couple, not on future activities of the couple.
I believe this was at a party organised by that horrible owner of 'Princess', Aad Ouburg (?). Usually Prince Carlos of Bourbon-Parma is there, I always suspected he was payed by the parvenu-owner to come, but as a van Vollenhoven-prince is coming now, I assume I was wrong. The Duke of Parma also attended the party, along with several dutch 'celebreties'.
I read an article about the party, apparently Prof Pieter van Vollenhoven was there as well, receiving a check from the organiser to support the victims of traffic accidents (a charity Pieter is involved in).
