A classical concert was organised after a giant cake with the name of Queen Paola on top.
Only Prince Laurent came 1,5 hour too late and missed the cake and the concert.
Princess Maria Laura, eldest daughter of Princess Astrid, seemed not to be present.
Nice detail on the last picture where Archduchess Anna Astrid started crying and Princess Claire took her keys out of her handbag and giving it to play with it and the child stopped crying
