Crime may not pay, but for Tatum O'Neal, it doesn't exactly cost all that much, either.

The former wild child actress has pleaded guilty to a misdemeanor charge of disorderly conduct stemming from her June crack bust. Prosecutors in turn dropped more serious charges, including drug possession.

To atone for her misdoing, Manhattan Criminal Court Judge Elisa Koenderman sentenced the youngest ever Oscar winner to spend two half-day sessions in a drug-treatment program and pay a $95 fee.

Should the 44-year-old Rescue Me star make good on both conditions of her sentence by Sept. 4, when she's due back in court, the case against her will be dismissed.

O'Neal turned down a nearly identical deal from prosecutors last month in which they offered her the chance to plead guilty to disorderly conduct and spend two days in a treatment. No word on what caused the change of heart.
