Jeffrey Epstein’s ‘madam’ Ghislaine Maxwell is secretly married but refuses to name her mystery spouse, US prosecutors have revealed.

The shock disclosure came as dead billionaire Epstein’s ex-girlfriend pleaded not guilty via video link to charges related to his sex trafficking ring yesterday.

Maxwell’s marriage was disclosed by US Attorney Alison Moe, one of three prosecutors on the case, at the detention hearing.

She spoke about the lack of transparency in Maxwell’s filings and asked who would co-sign her bond if she was given bail.
