Scheana Marie's relationship was a hot topic during Monday night's first installment of the season six reunion of "Vanderpump Rules" and during the show, a number of cast members questioned Robert Parks-Valletta's motives for dating [VIDEO] Scheana.

“[Scheana], I know we’ve had our issues, I know we have, but [you] put [your] heart and soul and effort into everything [you] did and the fact that my man is the only reason why Rob ever came around… Do you remember this? It happened three times," Lala Kent said. According to Lala, Scheana's former boyfriend, an actor, made a habit of making plans with his friends and changing them only if her boyfriend, movie and television producer Randall Emmett, was involved.

Was Rob Valletta using Scheana Marie to get close to Randall Emmett?

"[Robert Parks-Valletta] would say he’s going with a group of friends, Scheana would not be invited. She would be upset, understandably, and the only time he would come out and bail on plans is when my boyfriend would text him and say, ‘Do you wanna come out?’" Lala explained. Rob has a number of credits to his name but is certainly far from a household name. So, it wouldn't be too surprising if he had been motivated to spend time with Lala's boyfriend in hopes of landing an acting role in the future.

"[Scheana], I wanted to deck him," Lala Kent continued. "The way [Rob] treated [you] was not only not okay, but it was the behavior of someone who doesn’t want to be with someone else,” she added.

Rob Valletta dumped Scheana Marie after filming season six

After weeks of Scheana looking like an obsessed girlfriend [VIDEO] whose boyfriend simply isn't that into her on "Vanderpump Rules," Rob dumped her and broke her heart.

Then, for months, Scheana insisted to several media outlets that she and Rob would eventually get back together, get married, and start a family with one another. Unfortunately, that hasn't happened and a future doesn't seem possible for the former couple.

Since their breakup, Scheana has been enjoying the company of Robby Hayes but insists she's single.
