Teddi Mellencamp was spotted with her horse trainer, Simon Schroeder, after their alleged affair led to her divorce from Edwin Arroyave.
The "Real Housewives of Beverly Hills" alum was seen spending time with Schroeder while attending her daughter Slate's equestrian competition on Saturday.
Mellencamp was pictured snapping photos of the 12-year-old competing in Thermal, Calif., while Schroeder sat on a fence nearby watching the action.
The Bravo personality, 43, also shared clips from the event on her Instagram Story Sunday.
"@slate_mellencamp_eq fought her way around in her biggest class she has ever done. #proudmom," Mellencamp captioned one video of the preteen riding around the course.
Mellencamp also shared a video of Slate celebrating with her horse who sported a winning ribbon.
The outing comes just over a month after the mom of two announced her divorce from Arroyave, 47.
"After a great deal of care and consideration, I have made the difficult decision to file for divorce," Mellencamp wrote in a statement posted on Nov. 2.
"My priority is my children and ensuring that every care is taken with their privacy and wellbeing throughout this new chapter."
She added, "Making a public statement is not something I wanted to do, but in an effort to protect my family from undue speculation and rumors, I felt being open, honest and vulnerable was the best path forward."
Less than two weeks later, a source told Page Six that Mellencamp cheated on Arroyave several times with Schroeder.
"She filed for divorce from Edwin so that he did not have the chance to file and get her for adultery," an insider told the Daily Mail.
"It has been alleged that the marriage ended because Edwin cheated on Teddi, but it is actually the other way around."
Sources have also told Page Six that Arroyave had his own affair years before Mellencamp's was revealed.
The father of three allegedly had a fling with a woman named Missy between 2015 and 2016.
Three weeks after Mellencamp announced the split, she shared that she has "taken accountability" for her role in the downfall of her marriage.
She and Arroyave -- who tied the knot in 2011 -- share three kids: son Cruz and daughters Slate and Dove.
