Michael Jackson was allegedly so disoriented before he died, he should never have been allowed on stage - but a new lawsuit says AEG basically forced him to.

The late music superstar's three children - Prince, Paris and Blanket - and his mother, Katherine Jackson, are suing the concert promoter for strong-arming MJ.

AEG, the Jacksons allege, forced Michael Jackson into poor medical care from someone on their payroll (cough, Dr. Conrad Murray) and pushed him too hard.

Imposing a grueling rehearsal schedule that led to his death, AEG left MJ shivering and disoriented in a warm Staples Center in what was his final time on stage.

"AEG had legal duties to Michael Jackson to treat him safely and to not put him in harm's way," says the lawsuit filed by Michael's three children and mother.

"But AEG, despite knowledge of Michael Jackson's physical condition, breached those duties by putting its desire for massive profits over [health and safety]."

Jackson was to perform 50 shows in the UK last summer. He died June 25, 2009.

The lawsuit adds, somewhat unnecessarily: "Due AEG's actions and inactions, three loving children lost their father, a loving mother and father lost their son, siblings lost their brother, and the world lost its most celebrated entertainer."

The suit was filed Wednesday. Director Kenny Ortega, who was producing Jackson's "This Is It" tour (and later did the movie) is also named as a defendant.

Michael's father, Joe Jackson, is filing a separate wrongful death lawsuit against Murray. It is not clear if he is connected with this latest legal effort as well.

AEG had no comment and said that company officials had not yet seen the complaint pertaining to its hiring of Murray or treatment of the late King of Pop.

Murray allegedly gave the singer lethal levels of the anesthetic Propofol while treating Jackson, whose death was ruled a homicide, for his severe insomnia.

He has since been charged with involuntary manslaughter and is likely to argue that Jackson killed himself with a lethal dose while he was alone in the room.
