Lindsay Lohan freckles legs shorts filthy drug test rehab

Lindsay Lohan is staying faithful to her routine drug tests. Let's hope she passed with flying colors!

The 25-year-old starlet, wearing army green cut off jean shorts and displaying more leg bruises, left the drug testing facility in Los Angeles ... and kept her aviator-style shades on.

Lilo has had quite the busy week! First we got a glimpse of her newest project with furry friend Rico, then we got to see her Daisy Duke-inspired look while she headed to see Coldplay ... and now her routine drug test. Love the braid, Lilo!

Let's hope that despite not being signed on officially to the upcoming Gotti film, she ends up getting the role!

See more of Lindsay and her grunge-tastic attire ... after the jump.
