The pairing of two of America's most notorious white-collar female inmates has reignited interest in the lives of high-profile prisoners.

Ghislaine Maxwell has made an unexpected new friend at the prison she was recently transferred to. The convicted co-conspirator of late pedophile Jeffrey Epstein has reportedly grown close to notorious Theranos fraudster Elizabeth Holmes while locked up at Federal Prison Camp Bryan in Texas.

Elizabeth Holmes, the convicted Theranos founder, was caught on camera recently working out at a minimum-security prison in Texas where Ghislaine Maxwell was transferred.
