Titles of the Belgian Royal Family 2: 2023 -

Does this also apply to Astrid?

Yes, Princess Astrid is always styled by her own title only, with the predicate HRH (not HI&RH).

That has been the case since 1991, when gender-equal succession to the throne was implemented. Examples:

Her biography on the monarchy’s official website:

“Princess Astrid

Her Royal Highness Princess Astrid, Princess of Belgium, was born in Brussels on 5 June 1962. She is the second child of King Albert II and Queen Paola.”

And as you’ve mentioned her husband and kids are also only referred to by their Belgian titles, not their Austrian ones.

 

[meeralakshmi]

If Belgium decides to go by the Dutch example then a male consort will be HRH The Prince of the Belgians since a Dutch male consort is HRH The Prince of the Netherlands. However another difference between Belgium and the Netherlands is that Máxima is technically only HRH The Princess of the Netherlands whereas Mathilde is HM The Queen of the Belgians.

I stand corrected, queen consorts of Belgium are HM Queen X, Princess of Belgium while queens regnant are HM The Queen of the Belgians. It appears to be the same way in the Netherlands but in the Netherlands female consorts are now only supposed to be HRH The Princess of the Netherlands, the government just granted Máxima the courtesy title of HM Queen Máxima because they were afraid of having a princess consort while the wives of the other kings were queens. Since female consorts of Belgium aren’t HM The Queen of the Belgians I don’t think they would go with prince of the Belgians for a prince consort since it isn’t symmetrical with the female consorts’ titles (Dutch prince consorts are HRH The Prince of the Netherlands because Hendrik’s female predecessors were HM The Queen of the Netherlands). I think it’s more likely that they would go with HRH or HM The Prince Consort of the Belgians (ZKH or ZM de Prins-gemaal der Belgen/SAR or SM le Prince Consort des Belges/SKH or SM der Prinzgemahl der Belgier). However there is no reason they can’t go with HM King X, Prince of Belgium now that they’ve created different titles for queen consorts and queens regnant.

I am not at all sure about this, but it might be acceptable to refer to a queen consort socially as HM the Queen of the Belgians, even though her legal title is HM Queen X, Princess of Belgium (plus the surnames and titles she inherited from her father) as you said.

I still find it more likely that they would go with prince consort of the Belgians for a prince consort.
