Ghislaine Maxwell believes her ex-lover Jeffrey Epstein was murdered behind bars and lives in fear of facing the same unfortunate end, according to a new report.

“Everyone’s view including Ghislaine’s is Epstein was murdered. She received death threats before she was arrested,” an unnamed friend told The Sun.

A federal judge denied Maxwell bail on Tuesday and ordered the 58-year-old to spend the next year awaiting trial at the Brooklyn Detention Center, where she has been held since shortly after her July 2 arrest in New Hampshire.

The friend, who the Sun described as “in regular contact with Maxwell at her secret New Hampshire hideaway,” said the death threats spurred the British socialite to hire security guards, and led her to believe she may not live to see her trial.

The daughter of disgraced British medial mogul Robert Maxwell cried in court as federal Judge Alison Nathan refused to let her out on bail.

Maxwell faces charges that she conspired with Epstein to sexually abuse young women.

Her ex-beau Epstein died in custody Aug. 10 — after prison guards reportedly failed to keep an eye on him despite a previous suicide attempt.

New York City’s chief medical examiner later ruled the death a suicide.

Maxwell, like Epstein, is expected to expose celebrities and world leaders when she finally stands trial.
