(FILES): This January 27, 2012 file photo shows Paris Jackson arriving at the Michael Jackson The Immortal World Tour in Los Angeles, California. Michael Jackson’s daughter Paris, who tried to commit suicide this month, was the hardest hit by her father’s 2009 death, a co-guardian of the star’s three children said June 27, 2013. T.J. Jackson, a nephew of the late King of Pop, struggled to compose himself as he testified in court in Los Angeles, a day after the late singer’s 16-year-old son Prince took the stand. “I think the loss of my uncle has hit her at a different level,” he said of his cousin Paris, who remains in hospital after trying to cut one of wrists and taking 20 Motrin (ibuprofen) pills. “It’s tough. She was daddy’s girl. My uncle was her world,” he added. Michael Jackson’s mother Katherine is suing tour promoter AEG Live, accusing them of negligently hiring Conrad Murray, the doctor convicted of involuntary manslaughter for giving the singer the drug that killed him. Paris Jackson was rushed to hospital after trying to commit suicide at the family home in Calabasas, northwest of Los Angeles, on June 5. She had previously been treated for depression, and remains under medical supervision. AFP PHOTO / Files / VALERIE MACON
