Phillips, 48, thanked police for arresting her at Los Angeles International Airport in August, saying "they saved my life" in an address to Friday's court hearing.

The actress, the eldest daughter of late Mamas & the Papas leader John Phillips, was charged with possessing cocaine, heroin and a hypodermic needle or syringe after airport security found drugs packaged in balloons and plastic bags on her.

Phillips starred as Julie Romano in the CBS television comedy "One Day at a Time," which ran from 1975 to 1984. She battled drug addiction during her time on the sitcom and was later fired from the show after undergoing drug rehabilitation but then relapsing.

More recently, Phillips starred as a rock star mom in the Disney Channel series "So Weird."
