Desiree Hartsock's road to love may not have a happy ending. The Bachelorette host Chris Harrison called the season finale a "train wreck."

While on Kris Jenner's talk show Tuesday, Harrison teased that Hartsock's final days as the Bachelorette did not go as smoothly as previous seasons.

He revealed, "It's a disaster. It's a big dumpster fire that you're about to see ... Usually the sneak peeks are romantic, but this finale sneak peek was, 'Look at this train wreck that's about to happen.'"

"Des is crying. The guys are crying. Obviously, there is a huge emotional hurdle, to say the least, that's to come ... It's a rough ride to the finish. It is so crazy that it takes two weeks to unfold," Harrison revealed.

Just three men are left on win Hartsock's heart: Brooks Forester, Chris Siegfried and Drew Kenney.

The "Men Tell All" episode was shown on Monday to accommodate a special two-part finale, which will be shown over the next two weeks.
