Her notorious former boss has been languishing in federal prison where she's serving a 20-year sentence for pimping girls for Jeffrey Epstein.

But while Ghislaine Maxwell had to contend with rotting food, rodent infestations and belligerent inmates before her move to a cushier prison last week, her alleged 'lieutenant' Sarah Kellen has had no such worries.

Daily Mail can reveal an exclusive glimpse inside the gilded lifestyle enjoyed by Kellen, 46, who spent around a decade working as Epstein's personal assistant and was dubbed his lieutenant in court papers.

She's one of several glamorous female aides accused of arranging massages for the warped financier in various civil lawsuits – but has never faced criminal prosecution.

Kellen has spoken briefly in the past to claim she was Epstein's victim, rather than an accomplice, but didn't respond to multiple calls this week from Daily Mail.
