The travelin' popwreck and her sidekick, Sam Lufti, were spotted yesterday at -- where else? -- a gas station, where Brit stayed in her car as Sam pumped the gas -- isn't that the a paparazzo's job?

Before taking off, Brit's bud motioned for paps to come closer to the windshield and then started the wipers, splashing a few photogs with fluid. Then they went back to aimlessly riding around town.
