Look out, Kardashians (of E!’s “Keepin up with the Kardashians”), Brandy Norwood’s mom is comin’ after you.

Brandy’s mother, Sonja Norwood, filed a lawsuit yesterday, claiming that Kim Kardashian (and other members of the Kardashian clan) made some unauthorized purchases on Sonja’s American Express card.

At the time (2004), Kim Kardashian was a stylist and Sonja Norwood gave Kardashian permission to make “one (and only one)” purchase on the card.

The lawsuit claims that Kim Kardashian, as well as Khloe, Kourtney and Robert Jr., used the card and charged $62,793.83 in 2006 and $57,841.82 in 2007. (total charges: $120,635.65).

Why, oh why didn’t Brandy’s mom just cancel the card?

And let’s not forget it was Sonja’s son, Ray J, that appeared in the Kim Kardashian sex tape.
