Michael Jackson's Daughter Paris 'On The Verge Of A Meltdown,' Cuts Off Contact With Biological Mom Debbie Rowe

Paris Jackson has abandoned her mom Debbie Rowe, and pals fear Michael Jackson's daughter is headed for a dramatic relapse in a fight with the same demons that once drove her to attempt suicide.

"Everyone thought she was back on track," a pal told RadarOnline.com exclusively, "but now it looks like she's on the verge of a meltdown."

As RadarOnline.com previously reported, troubled Paris slashed her wrists and guzzled pills in 2013.

In the aftermath of the suicide bid, the late King of Pop's girl had grown closer to her mother. But now RadarOnline.com can reveal Rowe, 56, hasn't seen her daughter in over a year.

According to a family insider, relatives are terrified after Paris, 17, revealed her fragile state on social media.

"In video clips" with her 18-year-old boyfriend, Chester Castellaw, "Paris acts crazy," said the pal.

"She grabs hold of his face and sings: 'This is my baby, if you flirt with him, touch him, talk to him, think about him, or even look at him, I will slit your throat!'"

One psychologist who saw this footage concluded: "This is definitely not healthy."

Paris was planning to get hitched to her beau when she turns 18 next spring, a move that is terrifying her friends.

"I'm afraid if she tries to push Chester into marriage, he'll dump her, then all hell will break loose," warned the source.
