Being featured on an MTV reality show doesn’t pay enough, apparently. The Hills star Stephanie Pratt got a rude awakening at an MTV Video Music Awards after-party when she tried to pay for a bottle of champagne, only to have her credit card declined, according to Page Six.

Her solution was to ask Holly Montag to cover it, but Montag wasn’t too thrilled about that and refused to pay for the bottle.

“The waitress wouldn’t give her card back until she paid for the bill,” a source said. Pratt was later spotted at another party wandering around “hysterically crying,” another source said. “She was a total mess.”
