A “smoking gun” email allegedly links concert promoter AEG Live to the 2009 death of Michael Jackson was revealed in connection with the wrongful-death lawsuit filed by Jackson’s mother Katherine and his children.

The e-mail exchange between concert promoter AEG Live co-CEO Paul Gongaware and Jackson’s “This Is It” show director Kenny Ortega implies that Dr. Conrad Murray might have been under the gun to get an exhausted Jackson into performing over fear of losing his pricy $150,000-a-month gig as Jackson’s personal physician, according to CNN.

As The ENQUIRER reported Jackson died June 25, 2009,  a mere two weeks prior to the kick-off og shis booked 50-date comeback concerts at the AEG-owned O2 Arena in London.

The Hollywood Reporter says that Gongaware’s email read: “We want to remind (Murray) that it is AEG, not MJ, who is paying his salary. We want to remind him what is expected of him.”

Jackson lawyers are arguing that the email is evidence of AEG’s involvement in the King of Pop’s sudden tragic death.

Jackson’s kids Prince MichaelParis and Blanket, along with their grandmother Katherine, allege AEG Live’s pressure on Murray led to an overdose of  propofol, which the doctor had used to narcotize the singer into sleeping.

Murray was found guilty of involuntary manslaughter in November 2011 and is currently serving a four-year prison sentence.

This new trial is docketed for next month and will includes Jackson’s eldest son Prince, 16, and Dr. Murray  — who did not testify in his defense at his own trial — on the witness list.
