Lindsay Lohan has failed a drug test after being released from prison and may well be on her way back to the slammer.

The Irish American star wrote on her Twitter page “Regrettably, I did in fact fail my most recent drug test,”

She added “… Substance abuse is a disease, which unfortunately doesn’t go away over night. I am working hard to overcome it and am taking positive steps forward every day. I am testing every single day and doing what I must do to prevent any mishaps in the future.”

Lohan stated on Twitter that she would return to court in Los Angeles and “face the consequences.”

After her recent release she was ordered to take random drug testing twice a week, and attend drug counseling and behavioral therapy classes.

Now she's likely on her way back to jail.
