Britney Spears continues to keep the photographers busy, as they chased her around town. Yesterday's adventure included a trip to the gas station with her companion Sam Lutfi. Upon their arrival, Lutfi pumped the gas while Spears text messaged on her cell phone, smiled for the cameras, jiggled the dangling pumpkin hanging on her rear view mirror, and even bobbed up and down to the music playing in her car. The brunette seemed upbeat and in a good mood. After telling Sam to "hurry up," Lutfi proceeded to get in the passenger seat and turn on Britney's windshield wipers and spray to make sure the paps couldn't get a clear shot! This really seemed to amuse Britney, as she clapped her hands and laughed.
