The now-deleted video shows 20-year-old Jackson walking along a skyscraper ledge, with the caption: 'I almost died!'
A Jackson family relative told Page Six, 'She's lost it. She really has.'
According to Page Six, the Jacksons are worried about the young star and fear she is heading for a 'serious meltdown.'
'Everyone saw that video, and even though we all knew that she's now OK, watching it was so traumatic that nobody wants to show it to either Katherine or Joe,' said a family source.
Paris has previously attempted suicide three times and has a history of self-harm. She also claims to be a victim of cyber bullying, sexual assault and has struggled with self-esteem issues and sobriety.
The source told the publication they are not ready to host an intervention, stating: 'It's not happening, but everyone will regret it if she dies out there.'
