BEVERLY HILLS, CALIFORNIA: Teddi Mellencamp, known for her stint on 'The Real Housewives of Beverly Hills', recently made headlines for an unexpected and deeply personal reason—an affair that began in the stable and ultimately shattered her 13-year marriage to Edwin Arroyave.

Sources revealed that Mellencamp, 43, entered into a months-long affair with her German-born horse trainer, Simon Schroeder, before her divorce.

According to Daily Mail, it wasn’t just a fleeting romance. This relationship unraveled amid complex dynamics that rocked both their marriages.

The source claimed, “Karli thought it was suspicious that her husband was in Florida when she was giving birth.” This suspicion would eventually reveal a secret that would alter lives on both coasts.

In an astonishing turn of events, Schroeder was allegedly in Florida with Mellencamp while his pregnant wife, Karli Postel, was at home in California, preparing to deliver their second child.

When Schroeder returned, Postel found incriminating text messages on his phone which left no room for doubt.

Confronted with the evidence, both Schroder and Mellencamp confessed to their spouses. “Teddi promised it would not happen again,” according to the insider, but that assurance didn’t hold up for long.

Postel initially kept the affair from Arroyave, opting instead to try and mend her own relationship. However, after discovering further evidence that the affair was ongoing and had taken an emotional turn, she decided it was time to come clean with Mellencamp’s husband, leading Arroyave to discover the truth late last month.

It seems Mellencamp took control of the narrative quickly, filing for divorce before Arroyave could, reportedly to avoid an adultery claim against her.

“She filed for divorce from Edwin so that he did not have the chance to file and get her for adultery,” the source disclosed.

While rumors suggested that Arroyave had been unfaithful, sources claim it was actually Mellencamp’s affair that unraveled their marriage.

At the center of this romance lies a shared passion for horses.

Simon Schroeder had been training Teddi Mellencamp’s horse Totally—fondly nicknamed “Toad”—and their mutual enthusiasm for equestrian sport seemed to strengthen their bond.

Only months before the scandal broke, Postel had even posted on Instagram, “So beyond proud of Simon’s hard work with Teddi Mellencamp’s Totally!” and praised their “beautiful consistent rounds at the Devon Horseshow.”

Meanwhile, Mellencamp reportedly openly celebrated Schroeder’s contributions to her beloved horse’s training, at one point sharing her enthusiasm on social media: “I am Totally obsessed with you Toady baby boy…Thank you to @simonschroeder85 for the excellent rides.”

For a while, it seemed like a picture-perfect partnership, both in and out of the arena.

The bond between them was so palpable that Mellencamp even publicly thanked Schroeder’s training facility, Schroeder Sporthorses, for “always being team Toad.”

But the affair has left deeper implications in Mellencamp’s personal life. Her ongoing divorce battle has been contentious, with the pair clashing over custody and spousal support.

Edwin Arroyave and Teddi Mellencamp's high-stakes custody

Married in 2011, Teddi Mellencamp filed for divorce from her husband Edwin Arroyave on November 1 and cited October 20 as their date of separation. 

She allegedly filed for primary custody of their three children while Arroyave is contesting her request and advocating for joint custody.

Their legal wrangling has also extended to financial matters as Arroyave has requested that Mellencamp pay him spousal support, citing their prenuptial agreement.

In his response to her filing, Arroyave included that their prenup stipulated terms on spousal support, hoping the court would uphold it.

He also challenged her on legal costs, indicating both parties should bear their attorney’s fees, rather than solely him, as she had requested.

As the daughter of iconic musician John Mellencamp, Teddi grew up in the limelight, and her reality-TV fame on 'The Real Housewives' has kept her in the public eye.

Her subsequent appearances on 'Celebrity Big Brother' and 'Name That Tune' along with her popular podcast 'Two Ts in a Pod,' have built her a loyal following.

But even for a seasoned reality star, this latest chapter in her life brings drama to a whole new level—one that fans and onlookers never expected.
