A new tell-all book by an investigative journalist claims there was so much depravity in the Houston-Brown household Bobbi Kristina was introduced to drugs at a very early age.

Ian Halperin authored the book, “Whitney and Bobbi Kristina: The Deadly Price of Fame”. He describes the troubles in the household, and how the addiction of the mom rubbed off on the kid, who became addicted at an early age.

According to MailOnline:

“Bobbi Kristina, the ill-fated daughter of Whitney Houston and Bobby Brown, was a drug addict by the time she was 14 years old according to an explosive new book which reveals shocking new details about the short lives of the singing superstar and her only child.

Whitney & Bobbi Kristina: The Deadly Price of Fame, written by Ian Halperin, portrays Bobbi Kristina as a wild child who never stood a chance growing up in an environment where her own mother was too consumed by her own drug demons and sexuality issues to be a functioning parent.

According to Halperin, Bobbi Kristina was just 12 years old when she first accompanied her mother to rehab in Antigua in 2005.

Not long afterwards the troubled teen started needing her own stints in recovery wards.

Even before she was 15, Bobbi Kristina had already been committed to a psychiatric hospital for observation after trying to stab her mother before slashing at her own wrists, a relative told the author.

In seeking to find an explanation for mom Whitney’s addiction problems, Halperin revisits the often repeated speculation that the singer may have been a lesbian who chose to deny her true sexuality.”

Bobbi Kristina is still in a coma since she was found in a bathtub in February, supposedly of a drug overdose.
