CSI Creator's Wife: You Cancelled My Black Card!

The estranged wife of the creator of the "CSI" shows -- who is embroiled in an epic divorce -- has learned a truism first hand ... once you go black, you can never go back.

Jennifer Zuiker claims hubby Anthony Zuiker shut down her American Express Black Card. For those of you who aren't acquainted, it's something you will never have in your lifetime.

In the divorce docs obtained by TMZ ... Jennifer claims she had been regularly charging $40,000 - $60,000 per month on the Black Card, and now she's SOL -- left with a MasterCard with a measly $25k limit. FYI, with a Black Card, there's no limit, but cardholders must spend a minimum of $250,000 a year. That's not a typo.

But Anthony says, though his lawyer, disso-queen Laura Wasser, "Petitioner's concern is that she will no longer have a black Centurion Card to use because it is a status symbol." Priceless.

And it only gets better. Jennifer wanted Anthony to foot the $181,381 bill for the Alexander McQueen clothing bill he refused to pay for more than a year. It was the Fall, 2010 collection ... stupid.

It appears from court docs the parties have now settled this beef, but the divorce is still bitter and ongoing.
