Lindsay Lohan's mother has opened up about the actress' drinking and drug taking in an explosive new memoir.

Dina Lohan has penned the as-yet-untitled book with the help of a ghost writer and has included information on Lindsay's fall from grace - including five arrests by the age of 25 and numerous rehab stays - in a bid to make it a "best seller".

According to a draft of the prologue obtained by TMZ.com, Dina wrote: "I blamed her friends, her career and her handlers for an (sic) newfound lifestyle of partying excessively. Drinking, drugging and behaving irresponsibly became Lindsay's way of daily living-and it tore me up inside."

Dina also appears to admit she was wrong to send Lindsay to Hollywood alone as a young teenager in 2004 with only a chaperone for company while she stayed in New York to raise her other children Ali, 17, Cody, 14, and 23-year-old Michael Jr.

She writes: "How could I deny my daughter the chance of a lifetime? How could I hold Lindsay back from her dream of becoming an actress? So, I listened to others and sent my daughter to Hollywood with a few pieces of luggage and a chaperone."

Dina also reportedly speaks about the difficulties of juggling her roles as Lindsay's mother and manager.

Earlier this week, Lindsay was escorted from a Los Angeles courtroom in handcuffs after her probation was revoked but she was later released on $100,000 bail.

She will face trial on Nov. 2 which will decide whether she violated her probation, by skipping some of her community service duties - which were issued as part of her sentence for stealing a $2,500 necklace in January - and if found guilty could face up to 18 months in jail.
