Lindsay Lohan told David Letterman Wednesday that she's resisted indulging in drugs and alcohol as of late.

Letterman, who famously grilled the troubled pop tart in a memorable appearance a year ago, asked her, "You're clean and sober now?"

"Yeah, I feel really good," the 27-year-old redhead told Letterman, who reminded her of his own battles with the bottle as a recovered alcoholic for nearly 30 years.
