One of the frontrunners on this season of The Bachelorette is starting to look less like a winner after his sister was caught calling out Katie Thurston on Instagram. Greg Grippo from Katie’s season has already formed a strong bond with the Bachelorette, but Katie’s recent social media behavior and comment from Greg’s sister have brought up questions. There seems to be simmering drama between Katie and Greg’s family, and it’s casting doubt on the theory that Greg wins the season.

It was obvious how nervous Greg was from the minute he stepped out of the limo on night one, but something about him struck a chord with Katie. The Bachelorette gave Greg her first impression rose at the end of the night, and soon after, the pair had their first one-on-one date. Katie and Greg opened up about losing their fathers and connected on multiple levels. However, despite their budding romance, some fans think Greg could have ulterior motives for going on the show.

On a recent episode, another contestant, Thomas, revealed he had thought about being the next Bachelor, and it had the Chatty Broads podcast hosts posting memes. One, in particular, featured the first impression rose winner Greg with the words, “When the guy next to you is getting interrogated about wanting to be the bachelor and you’ve gotta pretend to be disgusted while hiding your acting career aspirations.” Greg works as a marketing sales representative, but he’s had acting experience in the past, and it has made fans think he could be on the show for the wrong reasons.

Surprisingly, Katie liked the post, though she quickly retracted it—but not before Greg’s sister Samantha picked up on it. “@thekatiethurston likes this post but was such a supporter of removing the toxicity and mean girls when she was on Matt’s season," Samantha commented, "You’d think if those intentions when[sic] genuine she’d have just as much of an issue with this post as well. Really disappointed in this." Katie has been known to troll fans with her social media activity, but with Greg’s sister issuing such strong words, maybe Katie and Greg aren’t currently together.

Many fans of The Bachelorette this season were rooting for Greg to win or become the next Bachelor, but these rumors of Greg going on the show to further an acting career could change their opinion of him. If Katie was actually engaged to Greg, she might have liked the post as a joke, but it’s unlikely that Greg’s sister would have responded with such a harsh comment. Although it’s not definitive proof, the dramatic Instagram exchange could indicate that Katie’s heart went to another man.
