It is nothing said about the CP-family, I don't think that the journalists didn't noticed them...
I found this on twitter a few days ago (19. Apr):
"Met with K Roberts of PSI and Crown Princess Mette-Marit of Norway, Melinda Gates foundation. Time to work for women..." But when this woman met MM and where, it is not written. (The woman live in Silicon Valley, so maybe the CP-family spent the vacation in California, as often in the past years.) (https://twitter.com/annikamickos
