A -LIST celebrities are quaking in their boots as Hollywood's most notorious fixer pens the ultimate tell-all, ripping the lid off the darkest sex and drug secrets he spent 17 years in the slammer to protect!

Former private eye Anthony Pellicano was the go-to guy to cover up the dirty truth behind stars' gilded images with a rolodex featuring the likes of Sylvester Stallone, Michael Jackson, Pamela Anderson, Tommy Lee, Roseanne Barr and many wheeler-dealer showbiz lawyers.

Now, Pellicano, 78, promises to dish all in a bombshell new book, sending Tinseltown into an absolute panic.

"He knows the most intimate secrets of the stars," proclaims a source. "It was his stock-in-trade. He was the guardian, the protector of those confidences, the man making sure they never got out." Pellicano had a knack for making unwanted stories and investigations disappear and keeping skeletons hidden in closets. But to defend a star's most intimate secrets, he had to know the ugly truth, making him one of the most dangerous people in Tinseltown.
