Dating Ashlee Simpson has its perks. People sing to you at gas pumps. For real, not pre-recorded.

Ash and Fall Out Boyfriend Pete Wentz hit up Parc last night, and while Petey drove them around in a dirty Land Rover, Ashlee paid the bills.

After leaving the club, Simpson went through her Prada purse to pay the valet, and later scraped the bag for cash to give to a homeless man -- who serenaded Wentz at a gas station pump.
