Stause and Oppenheim, who owns the Los Angeles-based real estate firm The Oppenheim Group with his brother, Brett, confirmed their relationship back in July, when Stause posted a photo of the two while on a romantic trip to Italy.
The photos—which were jam-packed with support by their costars—were captioned, “The JLo effect”. Of course, this served as a direct reference to the first official photos of Jennifer Lopez and Ben Affleck when they rekindled their romance after 17 years.
A month after Stause and Oppenheim made their relationship public, she revealed to E! News that the couple had actually already been dating for a couple of months before their announcement.
"It's just one of those things. You don't want to share with everybody and get all their opinions before you really know what it is," she told the publication.
"We really were really private and secretive for as long as we could until we realised the walls were closing in. People were getting a little savvy to it.
"We made it to a point where we're really happy to share it because we knew exactly what it was, so it's all good."
According to Oppenheim, the real estate broker the pair were already close before they became an item.
"Chrishell and I became close friends and it has developed into an amazing relationship," Oppenheim told People back in July. "I care about her deeply and we are very happy together."
Stause also confirmed that their personal relationship didn't change their professional one, as Oppenheim was and remains her boss.
"I just feel like the work/relationship dynamic," she told E! News. "It's not as complicated as people would think because we were best friends before and we work together all the time. It just kind of felt easy."
As fans of Selling Sunset know, their relationship looks to be the main plot line for their upcoming fifth season. But if the rumours are true, it looks like it may be the only time we'll see Stause and Oppenheim as an item.
In the meantime, you can binge-watch the most recent fourth season of Selling Sunset on Netflix.
