Britney Spears' Bizarre Dress Request

Britney Spears threw a hissy fit when an L.A. boutique was unable to meet her bizarre demands, according to a U.S. report.

The troubled singer reportedly stunned staff at the Betsey Johnson on Melrose Ave when she showed up earlier this month with a dress that she expected the store to copy so that she could wear it the same evening.

An eyewitness tells Gatecrasher, "the staff explained that they didn't have a dressmaker on call who could do it in time."

But the pop wreck didn't go away empty handed.

Continues the source: "The only thing she wanted to buy in the store was the yellow wig on a mannequin in the window. The manager eventually agreed to offer it to her for $100."

Meanwhile, Britney was caught on camera losing it after a pink-wigged reporter tried to give her a gift during a Starbucks run.

She can be heard shouting: "You are screaming in my ear, will you shut the fuck up!!"
