This drama-packed season of The Bachelorette comes to a close on Monday, and according to host Chris Harrison, it's totally possible that Bachelorette Kaitlyn Bristowe might not pick anyone!

While filming the new season of Who Wants to Be a Millionaire, Harrison opened up to ET about the wild season -- which has been filled with terrible contestants, awkward sex and testosterone-charged confrontations – and admitted that it's been "a wild ride."

"If ever there was a possibility of [a Bachelorette] just walking away with nobody, it's this season," Harrison revealed. "She's having such a tough time, and she's dealing with two guys who are kind of making more drama than there needs to be."

The two remaining suitors, Shawn Booth and Nick Viall, have been at each other's throats for most of the season and have continuously made their feud the dominating aspect of many of the conversations and dates that they've shared with Bristow.

"It's getting to the point where it's not even about Kaitlyn anymore," Harrison said. "It's about each other, and how much they dislike each other."

Aside from the season finale of The Bachelorette, fans are also clamoring to find out which of the axed suitors will become the next Bachelor, with Ben Higgins, Ben Zorn, and Jared Haibon all suggested as possible options.

So who is it going to be?

"A decision has not been made, contrary to popular belief," Harrison explained. "Yes, we have frontrunners, and yes, of course, the Bens are frontrunners - - both Ben Z and Ben H would be great bachelors. So would Jared. So would Cupcake."

"We really have an embarrassment of riches to deal with, and we have to see what happens with Nick and Shawn," Harrison added.
