For their first public event together, Stause stunned in a strapless black minidress that was complimented by shimmery earrings and matching silver heels. As for her boss-turned-beau, Oppenheim opted for a blue suit with a white dress shirt underneath.
Despite only flaunting their romance recently, OK! reported the two had been "secretly dating for a few months," as an insider explained: "They have always had a connection while working together."
The real estate broker also opened up about their new romance, telling PEOPLE the lovebirds "became close friends and it has developed into an amazing relationship." Oppenheim candidly added: "I care about her deeply and we are very happy together."
And while Stause and Oppenheim appear to be on cloud nine — the DWTS alum's rep also shared that the two are "happily together" — OK! exclusively learned their fellow costars aren't loving their shameless PDA.
While vacationing in Capri, Italy, last month, an insider said the two "were making out nonstop and generally acting like a pair of oversexed college kids," adding: "It was just too much for their cast mates to take."
The new flames jetted off to Europe with Oppenheim's ex and Stause's work bestie, Mary Fitzgerald, her husband Romain Bonnet, and Oppenheim's twin brother, Brett. While Fitzgerald is happily married and "made a big point at first to let everyone know she’s all for" Stause and Oppenheim's relationship, the insider said the 41-year-old is "starting to wish they’d take it down a notch."
Meanwhile, Stause's office foe, Christine Quinn, doesn't seem to be buying their relationship. The insider told OK! that the blonde beauty, 31, is “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."
Despite some backlash by those closest to them, Stause and Oppenheim appear to be too busy with their new relationship to mind the haters. “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," scoffed the source.
