Luxembourg: Official wedding book on the market 27 October 2012
I am not sure if the publisher has picked the best photo of Princess Stéphanie, though. Concerning the bride's title, I am still waiting for the decree which will make her Hereditary Grand Duchess. Nothing on Leguilux yet, and the official website of the Grand Ducal Family has not been updated since the wedding. The new member still has to wait for her own entry.

Hereditary Grand Duke Guillaume and Countess Stéphanie de Lannoy married
The religious ceremony took place in the Notre-Dame Cathedral today at 11 p.m., followed by a reception at the Grand Ducal palace. I was only able to follow the events on the Norwegian TV channel NRK1 up to bride's arrival at the cathedral. The weather was great and the crowd was impressive. The TV commentators could have been more informative when commenting on all the royals arriving for the wedding, though.
More details about the wedding and photos can be found at the official website, Gouvernement.lu and the local newspaper Wort.lu (German and English versions). See also NettyRoyal and Luxarazzi.
Countess Stéphanie de Lannoy became Princess of Luxembourg upon the civil wedding on Friday. The Grand Duke will soon issue a decree making her Hereditary Grand Duchess. As mentioned earlier, the new member of the Grand Ducal family has obtained Luxembourgian nationality by act 10 October 2012, published in Mémorial 15 October 2012 (no. 221, p. 3014). The preparatory works can be read here.

Norwegian TV coverage of the Grand Ducal Wedding after all
Today NRK informed me by e-mail that it had decided to cover the wedding after all. The TV guide is still not updated, but the information departement tells that the broadcast will last from 10 a.m. to 1 p.m. The religious ceremony in the Notre-Dame Cathedral in Luxembourg starts at 11 a.m.

No coverage of the Grand Ducal Wedding on Norwegian TV
I have been in contact with the Norwegian TV channels NRK and TV2 and have been informed that they will not cover the religious ceremony either. Certainly one can expect that a short glimpse of the ceremony will be shown during the ordinary news shows, but Norwegian royalty-watchers will not be able to watch the wedding in its entirety.
The royalty-watchers might be saved by Swedish TV, but as of now I have no idea if SVT or TV4 will broadcast the wedding or not.

Countess Stéphanie de Lannoy to take Luxembourgish nationality
The bill was filed in the Chamber of Deputies yesterday and is expected to be voted on in early October.
Wort.lu claims that the act will come into force on 20 October 2012, the day the religious celebration takes place in the Notre Dame Cathedral in Luxembourg. However, I can't find anything in the bill that explicitly states when the act is to come into force. It would also make more sense - at least to me - if the act comes into force on the date of the couple's civil wedding on 19 October. I guess we will know for sure when the promulgated law is being published in the legal gazette (Mémorial).
The bill (no. 6474 (2011-2012) can be read here.

Palais, le 26 avril 2012
Hereditary Grand Duke Guillaume was born in Luxembourg on 11 November 1981 and is the oldest child of Grand Duke Henri and Grand Duchess Maria Teresa, née Mestre.
Countess Stéphanie de Lannoy, who belongs to one of the oldest noble families of Belgium, was born at Ronse, Belgium on 18 February 1984 as the youngest of 8 children of Count Philippe de Lannoy and Countess Alix of Lannoy, née della Faille de Leverghem. Her paternal grandparents were Count Paul de Lannoy and Countess Béatrice de Lannoy, née Princess de Ligne, while her maternal grandparents were Baron Harold della Faille de Leverghem and Baroness Madeleine della Faille de Leverghem, née de Brouchoven de Bergeyck.
Her CV is impressive. Following her primary and secondary education in Ronse, Saint-Odile in France and in Brussels, Countess Stéphanie spent a year in Moscow where she studed Russian language and literature. She later studied Germanic philology at the Catholic University of Louvain, Belgium, before moving on to Berlin, Germany where she finished her master degree, focusing in her dissertation on the German influence on the Russian Romanticism. Then she took a further education course at the Wallonian Commercial office of the Belgian embassy in Berlin, before she started working for an investment company. Among her main interests are classical music - she plays the piano and violin - and literature, as well as sports (swimming and skiing). Besides French, which is her mother language, she speaks Dutch, English, German and Russian. A solid background for becoming Hereditary Grand Duchess of Luxembourg!
