The business ties between Erika Jayne and Lisa Rinna have been revealed as attorneys continue to investigate The Real Housewives of Beverly Hills star. Viewers have watched Lisa get into it with the other housewives due to her loyalty to Erika. While many have wondered how and when Erika and Lisa became so close, attorneys investigating Erika have revealed why. It turns out Lisa and Erika have a lot more in common than what they share on the show.

Season 13 has seen the emotional breakdown of Erika as she faces the reality of her divorce and impending legal woes. While filming the season, Erika shared what she could while keeping a tight lip about Tom's shady business dealings and her alleged involvement. Erika has continued to proclaim her innocence. But some of her co-stars are starting to wonder if the "Pretty Mess" singer is being honest. But amidst the scandal, Lisa remains a supportive friend of Erika. Her loyalty to Erika is so deep it reignited a feud with Garcelle Beauvais.

Erika has been busy tending to her legal woes and attempting to silence one attorney assigned to the case. After a judge recently denied her request to have Ronald Richards removed from Tom Girardi's bankruptcy investigation, the lawyer took to Twitter to reveal Erika's business connection to Lisa. "We can confirm that Lisa actually referred EG to her current biz manager," Ronald said. "There is a high level of trust between them. LR is defending her publicly. We will also confirm that the receivable owed by EJ Global is based upon value received."

The news comes a few weeks after Ronald threatened to expose Lisa and Erika's secret business relationship. "No more scams for the glam," he told Lisa after responding to a story where she blasted show alum, Camille Grammer. In recent weeks, viewers have also called out Lisa and her questionable loyalty to Erika despite having longer history with Garcelle and Denise Richards. Garcelle appeared unphased by Lisa's questioning of her after she offended Erika by asking about Tom. After Lisa asked Garcelle why she couldn't be more supportive of her friend, Garcelle reminded viewers how poorly Lisa treated Denise during her time on the show.

With Lisa and Erika sharing the same business manager, it could mean more trouble for Lisa if she continues to put herself in the middle of the drama. Sources have revealed how "betrayed" Erika feels by producers for her portrayal on The Real Housewives of Beverly Hills. Erika reportedly thinks she was hung out to dry for ratings and shock value. Footage of the show is already being brought up in court and could lead to prosecutors digging in to see what they can find. Erika's business team is also inching closer to appearing in a deposition where more can be revealed.
