At around 4:37 on the Day 3 Joey show, Doug Polk asserted that he was given info from a reliable friend of his regarding Robbi having a relationship with Rip. He claimed this friend told him that it was clear from their interaction at the table in Vegas that they had some kind of dating relationship.

Also, Rip appeared on Robbi's Zoom when he called in during the Day 2 show, so there's a good chance they were physically together.
