Do we know exactly if their Son Alexander is really divorced because of a noble tittle ?

There is no evidence for that, as far as I can see. The posted article does not mention a reason for the separation.

As I've said in an earlier comment, it's quite certainly because of other private reasons, which have nothing to do with Natacha's title or lack thereof.
The fact that her grandfather (or great-grandfather, I don't remember) might have embellished their family history (something which is true for other people who married into royal families, as it was pointed out in another comment) was known way before the wedding, and it still went ahead (in the presence of Alexander's whole family).
So, there must be other reasons

Does anyone else think Marie-Astrid resembled Taylor Swift in her youth?
