The Swedish Royal Court published today the guest list of Estelle's christening.
You can see the whole list here.
The most interesting ones:
Crown Prince Frederik and Crown Princess Mary
Crown Prince Philippe and Crown Princess Mathilde
Crown Prince Willem-Alexander and Crown Princess Máxima
And according to the speaker of the Swedish Court, Chris O'Neill and Sofia Hellqvist have also been invited.
The Dutch Royal Court confirmed that Crown Prince Willem-Alexander is one of the godparents!
The rest of the (probably 5) godparents are being announced tomorrow morning.
Too bad I'm writing an exam exactly at the time of the christening, but if you are able to see it, German ZDF is showing it and here is the official Swedish live stream.
