Source: Clifton Prescod/ Bravo Tension between two #RHOP stars spilled beyond the reunion couch and sparked an InstaStory clarification about a relationship timeline. On Sunday, a fed-up Keiarna Stewart shut down Jassi Harris on social media after she claimed she took her boyfriend, Greg, from his wife. During part two of the reunion, Andy Cohen pressed the women over their lingering tension that apparently included a silent subway sighting. Jassi said she and Keiarna saw each other on a train the day before taping and exchanged "nothing," as Kei ignored her.
