While vacationing in Italy with their Selling Sunset costars, Stause, 40, and Oppenheim, 44, “were making out nonstop and generally acting like a pair of oversexed college kids,” a source scoffs.
“It was just too much for their castmates to take,” insists the source. That includes Jason’s ex-girlfriend and Stause’s work bestie, Mary Fitzgerald, 41, “who made a big point at first to let everyone know she’s all for this pairing,” the source dishes. “But she’s starting to wish they’d take it down a notch.”
As for Stause’s office foe, Christine Quinn, 31, the source says she’s “convinced” the Days of Our Lives alum is “capitalizing on her relationship with Jason” to make herself the star of the show and that “it’s going to end badly.”
Not that Stause and her broker beau are paying their critics any mind. Adds the source: “They’re so caught up in each other and in flaunting their new relationship, they’re oblivious to how much everyone is rolling their eyes.”
OK! reported the two went Instagram official last month when Stause posted loved-up snaps of the two in Italy. Though the coupling may come as a shock to fans, an insider dished, "Jason and Chrishell have been secretly dating for a few months now," noting: "They have always had a connection while working together."
Stause and Oppenheim were first publicly spotted together in Vegas weeks before their official debut on social media. At the time, the new couple, along with Oppenheim's twin brother, Brett, Fitzgerald — who previously dated Stause's new man — and her husband, Romain Bonnet, attended a lavish dinner at FUHU.
Most recently, Stause and Oppenheim jetted off to Capri, Italy, with their costars, and both reality stars previously shared glimpses of their luxurious trip to their respective Instagram accounts.
