Hey, everybody! Lindsay Lohan's been fitted with an alcohol-monitoring anklet and must submit to random drug tests—and as a "close friend" tells Radar, she's loving the clean life!

And oh yeah: Radar also reports that yesterday, Lohan had all four of her wisdom teeth removed—because nothing helps a troubled starlet enjoy mandatory clean living like a humongous Percocet prescription.

Girl knows how to work it. Go Lindsay!
