*Michael Jackson’s doctor Conrad Murray is expected at an arraignment Tuesday, at which his lawyers say he will plead not guilty to involuntary manslaughter in the singer’s death, reports the Associated Press.

Murray’s lawyers said he will not seek a plea bargain and that they had no qualms about going to trial in spite of strong prosecution evidence at a preliminary hearing aiming to prove that the doctor’s gross negligence killed Jackson.

“We’re going to go to trial,” said defense attorney J. Michael Flanagan. “I think our case is really solid. We were very pleased with the way the evidence went at the preliminary hearing. … This should result in an acquittal.”

In other Jackson news, a new tell-all book about the King of Pop is coming from his former personal assistant and “lifelong friend” Frank Cascio. [See photo above.]

Cascio has a deal with William Morrow for “My Friend Michael,” due sometime in the fall, the publisher announced this morning.

According to Morrow, an imprint of HarperCollins, the book will offer an “uplifting and definitive” account of Jackson, who died in 2009, while noting the “terribly scarred” experience of fame.
