The Jackson family is not only blaming Dr. Conrad Murray for Michael's death, but concert promoters AEG, as well. X17online has learned exclusively that Katherine Jackson -- as guardian of her son's children Paris, Michael Jr, and Prince -- has filed a wrongful death lawsuit against AEG's top executives.

AEG President and CEO Tim Leiweke, Randy Phillips, Kenny Ortega and Paul Gongaware are named as defendants after an investigation into the concert promotion company began last year.

X17online has exclusively obtained the formal complaint that states:

    "By the nature of their contractual, joint-venture, and special relationship, AEG had legal duties to Michael Jackson to treat him safely and to not put him in harms' way. But AEG, despite its knowledge of Michael Jackson's physical condition, breached those duties by putting its desire for massive profits from the Tour over the health and safety of Michael Jackson."

The papers go on to say:

    "AEG's actions and inactions led to Michael Jackson's death on June 25, 2009 ... Due to AEG's actions and inactions, three loving children lost their father, a loving mother and father lost their son, the Jackson siblings lost their brother, and the world lost its most celebrated entertainer."
