Britney Steps Out – in Her Old Wedding Dress

SATURDAY JANUARY 12, 2008 05:00 PM EST

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.
