HOLLYWOOD: Celebrity blogger Perez Hilton has risked the wrath of Hollywood by taking aim at Drew Barrymore in his new tell-all book alleging the star's sober public image is a charade.

The Charlie's Angels actress endured a highly publicized battle with alcohol and drugs as a child star, but kicked her addictions with a stint in rehab in the early 1990s.

Earlier this year Barrymore insisted she doesn't claim to be sober, but she's found a "balance" that works.

Now Hilton has targeted the actress in his second tome True Bloggywood Stories: The Glamorous Life of Beating, Cheating and Overdosing, branding her a "f***** up mess."

In the book, Hilton admits he wasn't planning to mention Barrymore until an incident at a concert in Los Angeles changed his mind. He claims one of the actress' friends told him, "Those that can't do, criticize," and he replied, "You know, you are right, but at least I won't tell anyone what a mess (Drew) is..."

Hilton adds, "And I didn't (tell anyone). Until now." He goes on to write, "She is not the sober kitten that the main public may think she is."

And Barrymore's not the only star who will be fuming about the tome, which is released on Tuesday. Hilton also blasts Jennifer Lopez, alleging she set up a meal with her husband Marc Anthony and tipped off the paparazzi to dispel rumors their marriage was in trouble.

Hilton writes, "(Photographers) had received a call that basically instructed them where to be and what time and what to look for."
