Elizabeth Holmes, the disgraced former CEO of Theranos, has reportedly entered into an ego clash with reality TV star Jen Shah, from 'Real Housewives of Salt Lake City', after being incarcerated in the same Federal Prison Camp Bryan near Dallas. Prison insiders hint that an escalating rivalry for dominance is unfolding between the two high-profile prisoners.

Sources suggest that Shah was the reigning queen bee among the inmates until Holmes made her entrance. “Jen had been ruling the roost until Elizabeth walked in, and she's quite unsettled by someone encroaching on her turf!” a source revealed.

Holmes, 39, who is serving an 11-year sentence for her fraudulent activities at Theranos, joined the penal facility on May 30. Shah, 49, on the other hand, is midway through a six-year sentence for her involvement in a telemarketing scam targeting the elderly.

Prior to Holmes' arrival, Shah was known for her Shah-Mazing Abs workout classes and had exclusive access to luxury items from the prison commissary. However, since Holmes' arrival, sources suggest that the luxuries once reserved for Shah are now being divided.

The reality TV personality is reportedly not pleased with this development. “Elizabeth's spending on guards and commissary staff is seen as an apparent power play to clinch the top position, and Jen is undeniably unsettled by it," an insider explained.

While Federal Prison Camp Bryan is often referred to as the 'Club Fed' of women's prisons, it may soon turn into a battleground, at least for these two. "The facility may not be large enough to contain both their egos!" warns the source.
