Barely out the slammer, Lindsay Lohan is fearful that she could end up back in jail after failing a random drug test.
After learning that Lohan had failed the random drug test, Beverly Hills Superior Court Judge Elden Fox revoked the actresses probation on Monday and issued a no bail bench warrant requesting her to show up to the court hearing in person or face arrest
"She's scared she might have to go back to jail, this is a wake-up call for her in a way. In the past, she dismissed everything, never took it seriously and now she's like 'Oh [expletive], something bad could happen.' " a source told People.com.
During the summer Lohan spent 14 days in jail and 23 in rehab after missing court mandated alcohol counseling classes.
