Amanda Bynes reportedly cut her parents out of her life again as soon as her conservatorship ended earlier this month and they have no idea where she lives.

The 28-year-old actress, who was arrested for driving under the influence (DUI) on Sunday morning (28.09.14), moved out of Rick and Lynn Bynes' home in Thousands Oaks, California as soon as her conservatorship ended earlier this month and has allegedly stopped taking her anti-psychotic medication for Schizophrenia and bipolarity.

Rick told gossip website TMZ.com that he and his wife, who was temporarily placed in control of Amanda's welfare after she entered rehab last year following months of erratic behaviour, only learned about their daughter's latest arrest through the media and insists they didn't pay her $15,000 bail.

When asked about Amanda, he repeatedly said: ''We don't know.'' Insiders claim that the 'Easy A' star has started using marijuana again and is currently staying in Hollywood, but Rick said he thought she might have moved back to New York City.

The blonde beauty was arrested at 3am in San Fernando Valley area of Los Angeles after police discovered she was under the influence of a controlled substance, believed to be Adderall, while driving. She is set to appear in court on October 23.

Amanda was previously charged with DUI in April 2012, but the charge was dropped in February this year and she was sentenced to three years of probation for reckless driving as part of a plea deal.

She also had her driving licence suspended in September 2012 following two alleged hit-and-run charges in April and August of that year, but the case was later dismissed following a financial settlement between herself and the victims. The actress' licence was restored in April after she attended alcohol education classes for three months, as part of her plea deal in February.
