You know what they say. When the going gets tough, the 85-pound weaklings go hiking!

The sickly Nicole Richie, who was arrested on charges of driving under the influence early Monday morning, is determined to stay the course as she takes in some fresh air with an unknown male companion in the Hollywood Hills on Sunday. No word on whether she's taken in any food yet this month.

While this fabulous Nicole Richie mug shot is pretty damning proof of the downward spiral that has become her life, she can at least take solace in one thing: She's not constantly photographed wearing no pants, slinging illegally-obtained prescription drugs out of the Hyde bathroom and dating some loser like J.R. Rotem.

Come on, Britney!
