The Selling Sunset costars appeared to be on cloud nine together, as they shared giggles and smiles. At one point, Stause held onto her man during their visit to the Colosseum and Roman Forum.
Their public outing comes days after Stause and Oppenheim went Instagram official, with the brunette beauty sharing affectionate photos of the two in Italy. Though their debut as a couple may have 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, 40, and Oppenheim, 44, were first spotted together on July 4 in Las Vegas, where they attended a lavish dinner at FUHU with their costar crew including Brett Oppenheim, Mary Fitzgerald — who previously dated Stause's new man — and her husband, Romain Bonnet.
"The whole group was having a lot fun enjoying their night out, eating, laughing and having drinks together while checking out the new property," a source said of their night out.
The gang then reportedly headed to an event Miley Cyrus was throwing at Ayu Dayclub, during which Stause and her boss had their hands all over each other, a source claimed. "Jason often put his arms around Chrishell as they sang along to Miley's songs together," said an insider.
Most recently, OK! reported the reality star couple jetted off to Capri, Italy, with costars Brett, Fitzgerald, Bonnet and pal Tina Louise.
While enjoying their romantic getaway, Stause — who was married to ex-husband Justin Hartley before they called it quits in 2019 — has shared a slew of photos and videos of the lovebirds and their crew. The reality star most recently posted a selfie to her Instagram Story of herself and Oppenheim seeing the sights.
The founder of The Oppenheim Group reposted his new flame's Instagram Story and shared several photos of the group enjoying a family meal, flying in a helicopter and relaxing on a boat.
