Paris Jackson Huddles With Mom Debbie Rowe Before Trial

Michael Jackson's famous daughter/plaintiff, Paris Jackson, spent time with her biological mom Debbie Rowe, on the eve of what promises to be a very difficult wrongful death trial.

As we first reported ... Paris has bonded with Debbie after years of separation. The 2 are spending a lot of time together, and we're told both genuinely want the mother-daughter relationship they never had while Michael was alive.

Speaking of Michael, the family's wrongful death trial kicks off today. Katherine Jackson and MJ's 3 kids are suing AEG Live, claiming the company was negligent in hiring and supervising Dr. Conrad Murray -- who killed the singer with a massive overdose of Propofol.

MJ's family will have an extremely difficult time winning this case, for the following reasons:

-- MJ had a doctor-patient relationship with Murray before AEG came into the picture. Jackson first hired Murray to treat his kids, and then used him for personal issues. Murray had given Jackson Propofol before AEG was involved.

-- MJ was a drug addict who had doctor-shopped for Propofol for well over a decade. He knew the drug so well, he often wanted to help in the administration of the drug.

-- MJ was secretive about his relationship with Murray, never telling anyone from AEG or the "This Is It" honchos that Murray was fueling him with Propofol almost every night for 2 months.

-- AEG execs are not doctors, and arguably they're in no position to tell a doctor what to do.
