'The Bachelorette' bachelor John Hersey: Defending Greg Grippo's behavior during Katie Thurston split is "extremely unhealthy" By Elizabeth Kwiatkowski, 08/04/2021 The Bachelorette bachelor John Hersey has called Greg Grippo out for shocking behavior and insisted no one should defend Greg for how he had treated Katie Thurston during their final breakup conversation. ADVERTISEMENT John, a California bartender whom Katie eliminated in Week 2 of The Bachelorette's seventeenth season, took to Instagram Stories on Tuesday and slammed anyone who's been sticking up for Greg ever since Katie appeared to accuse Greg of gaslighting her on the show. "I very rarely do this sort of thing, but I wanted to address a topic that is being very heavily discussed right now. Let me start by saying that I am so grateful for the incredible friendships I made while on this season," John began in his post.
