Ghislaine Maxwell is secretly married but has refused to disclose her husband’s identity to FBI agents, a court has heard.
US Attorney Alison Moe, one of three prosecutors on the case, revealed Maxwell had a spouse while questioning who would co-sign her bond at a bail hearing in New York.
She told the courthouse late on Tuesday: "In addition to failing to describe in any way the assets of the proposed co-signer of a bond, the defendant [Maxwell] also makes no mention whatsoever about the financial circumstances or assets of her spouse, whose identity she declined to provide to pretrial services.
"There’s no information about who will be co-signing this bond or their assets, and no details whatsoever."
The 58-year-old wiped tears away as a judge refused her the proposed $5million bond, backed with $3.75million in property in the UK, and ordered her to be detained until her full trial, provisionally set for July 2021.
Maxwell's legal team had argued she would be confined to a 'luxury hotel' in the New York area, surrender all her travel documents and be subject to GPS monitoring.
But Judge Nathan ruled the British socialite was a significant flight risk, citing her “substantial international” ties and “extraordinary financial resources”.
Maxwell is accused of grooming girls as young as 14 for Epstein to abuse between 1994 and 1997, a period when she was his girlfriend.
Attention will now turn to who the unnamed spouse could be. According to the court hearing, Maxwell used the alias "Jen Marshall" and posed as a journalist when viewing a hideaway in Bradford, New Hampshire, (below) which she bought for £800,000 in November last year.
She was arrested at the house last week in an early morning raid by FBI agents and police.
Estate agents claimed she was accompanied by a man with a British accent who used the pseudonym “Scott Marshall”.
A source familiar with the case told ABC News that the disclosure about her marriage was made deliberately as part of the prosecutors’ argument that Maxwell has not been forthcoming about her circumstances and finances since her arrest.
During the two hour and 20 minute hearing at Manhattan's Federal Court, Maxwell appeared via video link from the Metropolitan Detention Centre in Brooklyn.
She will now return to the fortress-like Metropolitan Detention Center in Brooklyn where she has been given paper clothes to ensure she doesn't kill herself, following Epstein's death in custody last summer.
She faces up to 35 years in prison if convicted.
