Paris Jackson has been left “utterly distraught” by new documentary Leaving Neverland, which details sexual abuse allegations against her late dad Michael Jackson.

The 20-year-old daughter of the pop icon is understood to have checked herself into rehab for mental health issues triggered by the film, which premiered at Sundance Film Festival last week.

She “suffered a complete meltdown” an insider told The Sun.

“She’ll resurface sooner or later but certainly isn’t ready to face the cameras on a subject that keeps breaking her heart.”

The details of alleged abuse of children at the hands of the pop star, who died in 2009, are so disturbing counsellors were present on-site at the Sundance screening.

Michael Jackson denied repeated allegations of sex abuse until his death, and his estate issued a statement slamming the documentary after the screening last week.

“Michael is not here to defend himself, otherwise these allegations would not have been made.”

Paris was 11 years old when her pop icon dad passed away. Her mother is Australian woman Debbie Rowe, who was married to Jackson from 1996 – 1999.
