Britney goes shopping in her wedding dress

Something borrowed, something ... leased?

Revisiting her wedding look, Britney Spears donned one of two dresses from her Kevin Federline nuptials to go to a car dealership last week with her new paparazzi friend.

Spears, 26, and Adnan Ghalib, 35, arrived at the Keyes Mercedes-Benz dealership in the San Fernando Valley on Friday afternoon, surrounded by the now-familiar pack of photographers that once contained Ghalib.

The twist was the pop singer was wearing the same lacy, short dress from her 2004 wedding to Federline – her second walk down the aisle following her 55-hour marriage to Jason Alexander.

Spears's own Mercedes was impounded last week after she abandoned it on the road when it blew a tire, but this trip to the dealer was for Ghalib, her constant companion since her meltdown.

"They came in to get an estimate for a new car for him," a sales associate says. "He drives a rental car now. ... He was looking into the different lease and purchase options for sport cars."

By the time they started talking business, Spears had covered up with a trench coat, the sales person says.

"She didn't talk at all and it didn't seem like she was getting the car for him," the sales associate says.
