Apparently, Nicky Hilton's got little else to do, so why not be Paris' personal driver?
TMZ caught Paris shopping for her size 11 shoes at Diavolina on Robertson Blvd. yesterday -- checking out the merchandise while Nicky texted away while waiting for sis in the car. Paris eventually came out, without purchases, and walked over to the gas station where Nicky was parked.
Crack a window for her next time!
