I've recently seen on several wikis this picture supposed to represent a Norn Queen

Yet I'm kinda struggling to find the confirmation that this is an official design, as it is not featured in any Tyranid codex nor anything else related.
Does anyone know by any chance its source?

Isn't this just an Alien Queen?

If it isn't I can't recall it from any GW publication.

It's more blatant Hive tyrant than queen and probably fanart.

(Alien queen has two round "cutouts" in the sides of the head carapace - in effect making the head look like a shield that you can brace a weapon in).

Possibly concept art for the 'Alien Brain Pod' by trollforged miniatures. The body in the pod in that art does look quite different and more tyraniddy. But I wouldn't be surprised if they changed it a little between concept and final design to reduce the chance they had an army of lawyers thrown at them.
I think they released this thing a little while after the 5th edition tyranid codex, and a bunch of people were using it as a proxy Doom of Malantai.

It's fanart by wormwood. It's also only part of his Norn Queen design.
