Lindsay LohanFour days after a judge briefly detained her for failing court-mandated drug tests, Lindsay Lohan has entered a live-in rehab facility in Southern California to seek help for substance abuse, TMZ is reporting.

No other information is given in the report, other than that the 'Mean Girls' actress will likely stay at the facility until her next court date on Oct. 22.

The actress dominated headlines going into last weekend when she was denied bail by Judge Elden Fox, taken into custody, then granted bail by the day's end after a different LA County judge overturned Judge Fox's ruling.

Lohan, 24, was behind bars during those hours due to an admitted relapse: She recently failed two crucial drug tests, for cocaine and illegal Adderall use. According to the terms of Lohan's probation, a failed drug test means she will spend another 30 days in jail.
