Less than a month after getting out of rehab, fallen starlet Lindsay Lohan might be going back in. Despite being warned by Elden Fox—the new judge on her case—that a failed drug test would result in a month in jail, she failed, a source told People magazine. An insider revealed that the court-mandated drug test occurred “in recent days.” Lohan is subject to twice-weekly court-mandated drug tests and intense outpatient treatment pending her hearing on November 1. According to People, the actress could face up to 30 days behind bars. When Us Weekly addressed Lohan regarding the claim, she replied, "I'm fine" and called the report, originally posted by TMZ, "nuts."
