Radar Online reports:

An insider who passed a polygraph test says that Paula walked in on the masseuse and Robin and literally caught him with his pants down. At first Robin tried to act as though his affair was no big deal. He couldn't understand why Paula was so upset, a source says, since she's been fooling around with Jasmine too.

That reaction angered Paula even more. "Robin pushed Paula to allow Jasmine into the bedroom with them in order to spice up their sex life, and she reluctantly agreed in an attempt to keep him happy," the source explains. 

Paula banned Jasmine from their home and tried to put the situation behind her as a one-time fling, but her suspicions kept getting to her because she believed that the affair has been going on much longer.

People started talking about Robin and Jasmine back in 2012, when Paula was in Miami shooting a movie Star reported. Though nothing was said, some people noticed the chemistry between Robin and Jasmine. "Paula was accepting of her, but a lot of people thought that Jasmine wasn't to be trusted," the source says. "Even after she was banned, she would visit Robin when Paula wasn't around."
