Hello wizard boy,
You've been reading about mythological creatures again, haven't you?
From the Clerk's Tale:
O noble wyves, full of heigh prudence,
Lat noon [no] humylitee youre tonge naille:
Ne [nor] lat no clerk have cause or diligence
To write of yow a storie of swich [such] mervaille,
As of Grisildis [Griselda], pacient and kynde,
Lest Chichivache yow swelwe [swallow] in hire entraille.
So I guess Britney doesn't fit into the good wife category. The chichivache liked to feast on obedient and kind wives.

btw, re your Harry Potter endeavours, have you read
Fantastic Beasts and Where to Find Them, also by JK Rowling?
