On 23 February a special Te Deum was held in Belgium at Laeken in honor of deceased members of the Belgian royal family. Many members of the Belgian royal family were present.
Princess Marie-Astrid together with her husband Archduke Carl-Christian were also in attendance. They were accompanied by Archduke Christoph and Archduchess Gabriella (it is possibly Marie-Christine the only picture I saw had a chin and wisp of blond hair). The Archdukes assisted the Princess when she dropped something (her tissue?). It is always disheartening to me that the lovely princess is so rarely used by the Luxembourg family. However, I'm glad that they attend all the Belgian events.
PPE has a gallery of pictures.
