Phillips, 48, has battled an addiction to drugs for years.

Best known for her work on the 1970s and 1980s sit-com "One Day at a Time," she also appeared in the Disney Channel series "So Weird" in the 1990s.

Police said the daughter of The Mamas and the Papas lead singer John Phillips was arrested Wednesday for alleged drug possession at Los Angeles International Airport.

E! Online reported she was released Thursday afternoon after posting bail, following a night in jail.

Phillips told police officers she had a "drug problem" after she allegedly was discovered to have small amounts of both cocaine and heroin on her as she tried to get through airport security, E! Online said.
