Woah, woah, woah... Netflix has pulled the cameo of all cameos out of their bag.

The crossovers of all crossovers is upon us this December, with the arrival of the final chapter in the 'Chilling Adventures of Sabrina' on Netflix.

The witching hour kicks off once again on New Year's Eve, and it looks like there will be some faces from the past arriving on our screens for the finale. Complete with a laughter track and all.

As you can see from the brief clip below, Beth Broderick and Caroline Rhea, who played Sabrina Spellman's trusted aunts Zelda and Hilda in the original 'Sabrina the Teenage Witch' 90s series will be reprising their roles for what appears to be one particularly mind-bending episode.

The actors starred in the comedy series from seasons one through to six, only appearing as guest stars during the final seventh season.

It's likely their return to the franchise will only be a for a brief moment of respite in what Netflix has assured us will be one climactic finish to their teen series. Season four will see Greendale become overrun with The Eldritch Terrors, who are set to be the menacing new antagonists.

All we need now is Melissa Joan Hart and Nick Bakay to reprise their roles as Sabrina and Salem, and we'll have a full house on our hands.

Here's the clip.
