Katherine Jackson: 'Paris Was Suffering & We Didn't Know It'

For the first time since Paris Jackson's suicide attempt, her grandmother and guardian Katherine Jackson is opening up on the teenager's trauma.

"I guess she was suffering and we didn't know it," Michael Jackson's  mother told 60 Minutes Australia.

Her lengthy interview aired Sunday night and was heart-wrenching to watch.

Often shedding tears, the Jackson family matriarch was asked directly if Paris had attempted suicide in June.

"Yes, it is true," Katherine responded.

She also revealed that after Michael's 2009 death, at the mortuary, Paris kissed her dad and told him, "I don't want to live without you."

And after moving in with her grandmother, Paris covered her room with memories of her dad.

"She had to have his pictures everywhere in her room," Katherine said.

Fortunately, Paris is doing "much better" and is continuing her treatment at an unnamed school.  Adding to her recovery, Katherine confirmed, is the much improved relationship between Paris and her biological mother, Debbie Rowe.
