Lindsay Lohan may be suffering a bitter break-up but that doesn't give her an excuse to take it out on the environment.

The Mean Girls star was spotted littering out of her pal's Bentley as she left the Byron & Tracey Salon in Beverly Hills yesterday.

The actress dropped a flyer out of the car window before speeding off.

Meanwhile, since her split with Samantha Ronson, Lindsay's worried grandmother has urged the star to reach out to her family.
