“We go to dinner [at] Vanderpump Paris," recalled the former pageant queen. “Oliver, our waiter, brings out the fancy drinks. Lala mentioned Oliver and she was like, ‘He has the cutest smile ever.’”

She added, “He met up with us and we’re both having a very engaging conversation and I turn to Lala and I’m like, ‘Wait Lala, I think he’s really cute too.’ And she goes, ‘You know what Raquel? I’m not going to do anything with him. I’m going to give you the green light.'”

With Kent’s approval, Leviss admitted she and Saunders started “making out on the dance floor.” This revelation appeared to make Sandoval, 40, uncomfortable as he sat next to his then-girlfriend Madix, smiling awkwardly.

Madix, 37, at this point had no idea about how complicated the moment was, and told Leviss: “Well good for you, I’m glad you made out with someone.”

However, Leviss’s night in Las Vegas took a turn. She explained, “Then all of a sudden it turns into like this whole ‘We really need to talk Raquel, I don’t approve of your actions lately.’”

She added, “Lala goes, ‘Honestly Raquel,I wouldn’t feel comfortable having you around my man.’ And I said, ‘Well it’s a good thing you don’t have one.’”

AsVPRviewers now know, the 32-year-old Give Them Lala founder was one of the first of Leviss’s costar to pick up on her growing closeness with theSchwartz and Sandy’sco-owner.

At that time, though, more issue would arise over Saunders’ single status, triggering weeks of arguments in which Kent and Levisseach called each other a “mistress.“Behind the scenes, Sandoval and Leviss werecarrying on a secret relationshipunbeknownst to Madix (with Leviss evensuggesting at one point they become a throuple).
