Actor Brad Renfro pleaded guilty Thursday to attempted possession of heroin in a case stemming from his December arrest during a sting in the Los Angeles Skid Row area. He was given three years' probation and must enter a rehab program.... Film director Lee Tamahori pleaded no-contest to criminal-trespass charges, in return for having a pair of prostitution charges against him dropped. Tamahori was arrested Jan. 8 for allegedly soliciting an undercover cop while wearing a dress and, um, a black wig.
