Paris Hilton spent Monday night escorting younger brother Barron around town - making stops at Katsuya, Hyde and Villa in West Hollywood.
The Hilton siblings were accompanied by oil heir Brandon Davis, and, fortunately, the threesome was smart enough to hire a driver for the evening.
Meanwhile, hiring a driver to avoid another DUI isn't the only intelligent choice being made by Miss Hilton of late.
The 26-year-old recently told how she's doing her part for the environment, saying, "I changed all the light bulbs to energy-safe light bulbs, and I'm buying a hybrid car right now. Little things that people can do every day to make a huge difference."
Enjoy the pictures of Paris out at Villa with Brandon and Barron (December 17).
