Lorde is a 45-year old geologist ... at least according to last night's episode of "South Park" -- and the pop star has spoken out ... saying it's pretty damn weird.

The episode -- named "The Cissy" -- took on transgender equality ... and Stan's dad Randy Marsh revealed he's actually Lorde.

Randy eventually feels comfortable being Lorde and makes a song about it. The song unites "South Park" and everyone learns to accept people for who they are.

Lorde tweeted about the episode this afternoon saying, "i have officially been the subject of 2 south park episodes and that is weird and cool."

She adds the song at the end of the episode was actually sung by Sia.
