Lindsay Lohan ordered to court over failed drug test

LOS ANGELES (Reuters) - Lindsay Lohan was ordered on Monday to appear in court after admitting that she failed a court-ordered drug test a few weeks after being released from jail and a subsequent stint in drug rehabilitation.

Los Angeles court officials said Lohan’s probation had been revoked and a formal warrant for her arrest had been issued, but held until Friday, when she must appear in court.

Friday’s hearing is expected to determine whether the “Mean Girls” actress will return to jail.

Lohan, 24, whose career has been derailed by drugs and alcohol problems, admitted in a Twitter message on Friday that she had failed a random drug test but said she was working hard to overcome her battle with substance abuse.

Celebrity new website said she had tested positive for cocaine.

Lohan served two weeks in jail in August followed by 22 days of a three-month residential drug rehab program after violating her probation on a 2007 drunken driving and cocaine conviction.

Following her release from rehab, the court order had required Lohan to undergo random twice weekly drug tests and counseling, and she was warned by a Beverly Hills judge that any positive results would see her back in jail for 30 days.
