Amanda Bynes' parents have been granted a temporary conservatorship over the troubled actress as she continues to receive treatment in a psychiatric hospital. The Easy A star's mother, Lynn, and father, Rick, won their bid to take over control of Bynes' legal affairs and finances in a California court on Friday (09Aug13). The conservatorship will remain in place until 30 September (13), when a judge will decide if the arrangement will be made permanent, reports TMZ.com. During Friday's court proceedings, which Bynes did not attend, the judge also approved doctors' request to keep the 27 year old under medical supervision for another 30 days, despite opposition from her lawyer. Bynes was placed on an involuntary psychiatric hold last month (Jul13) after allegedly starting a small fire on a driveway in her parents' neighbourhood of Thousand Oaks, California. The 72-hour hospitalisation, also known as a 5150 hold, was previously extended to two weeks and now the embattled star must remain under doctors' care until September (13). The court development is the latest in a string of woes for the actress - she is facing a charge of driving under the influence after allegedly crashing her car into a police vehicle last year (12), and a further accusation of driving on a suspended licence just months later. She is also facing counts of reckless endangerment, tampering with evidence and possessing marijuana after reportedly throwing a bong out of her New York apartment window during a police raid in May (13).
