Paris Jackson lost her soul when her father died ... so said Michael Jackson's ex-wife Debbie Rowe on the stand today, breaking down into tears.
Debbie was testifying for AEG in the wrongful death lawsuit Thursday, when the subject turned to MJ's 15-year-old daughter and her recent suicide attempt.
Debbie said she had been in touch with Paris every day until June 5, when paramedics were called to the Jackson mansion in Calabasas after Paris downed a bunch of Motrin and cut herself with a butcher's knife.
Debbie said Paris had been "devastated" by her father's death and that's what caused the suicide attempt. Debbie added, "She tried to kill herself ... She has no life. She doesn't feel she has a life anymore."
Paris is currently at an undisclosed residential treatment center outside California.
