However, a clue in CAOS may suggest that Sabrina Spellman is related to the baddest b*tch in the AHS series: Madison Montgomery, aka Emma Roberts.

It shows Hilda's line from episode 1 ("He could've been a movie star if he'd chosen, like cousin Montgomery"), where she is talking to Sabrina about how handsome her father was.
The comparison pic of Madison shows her saying, "Madison Montgomery, movie star."
The publication also pointed out that the "Montgomery" name could also be referenced to the actor Elizabeth Montgomery, who was a star in the '60s show Bewitched.
However, the thought of Sabrina and Madison being related is way more appealing. We love a conspiracy theory!
