Britney Spears has shown the world how gullible she is by giving her husband an American Express Black card, also known as the Centurion. An invitation-only card with a hefty $2,500 annual fee, the Centurion gives holders automatic first class flight upgrades on all airlines and offers access to airport clubs and personal shoppers at luxury stores. It features a personal concierge and travel agent. If you can think it up, you can probably get it with an AmEx black card.

In the 1980s tales of the “Black” no-limit American Express card were just urban legends, but Amex responded to the black card lore and decided to offer it to high rollers. Now rappers name-drop it in songs, and uber-rich people have the opportunity to go deeper in debt than they ever dreamed possible.

By giving K-Fed access to her Amex Centurion, Britney is essentially letting him empty any bank account he wishes. He has the opportunity to spend lots of money in a very short time with a single phone call. Here’s what people have done with the Centurion card:

Hey maybe AmEx can help K-Fed with his rapping career! He should call them up now that the black card is in his posession. They seem capable of hooking people up with just about anything.

Seriously, though, Britney is trusting her fortune to a guy who has a custom Ferrari worth more than a quarter of a million dollars, and a Maserati worth at least six figures. He also reportedly bought a $30,000 watch without asking Britney. Now is that the kind of person you would trust with your money?

Here’s Britney dropping off a mini Escalade at her recording studios for Sean Preston to play with while she’s there, and Kevin getting a haircut and pumping gas. Sean Preston, 11 months, took his first steps in Las Vegas last week. So now he must be old enough to drive a car, right?
