WATCH: First ‘American Horror Story: Apocalypse’ trailer reunites all your favorite witches

Worlds will soon collide for the latest installment of American Horror Story, and by the looks of the first trailer, trouble starts early.

AHS: Apocalypse, which premieres September 12 on FX, combines the stories of 2011’s Murder House and 2013’s Coven.

“It’s the end of the world,” we learn at the opening of the trailer, as an air raid siren blares over the charred remains of Los Angeles.

OK, so they’re jumping right into the “apocalypse” theme, and we’re so on board.

There’s a first glimpse of Jessica Lange’s Constance, Sarah Paulson’s Supreme witch Cordelia, and Emma Roberts’ Madison Montgomery — all characters reprised from Coven.

And there’s one very special addition. Dame Joan Collins pops up in the trailer as glammed-out grandmother of Evan Peter’s character.

Here they are looking surprised on a private plane:
