A preview for the finale obtained by Entertainment Tonight has even shown Becca crying to the cameras, "I feel terrible. I feel like such a monster."

"It's gut wrenching," Chris told ET ahead of the three-hour finale event on Monday, August 6. "It's absolutely gut wrenching."

"What happened in the Maldives, it's beautiful and it's brutal at the same time," the host continued. "It's crazy to have the same all in one storm."

Since Becca announced at the start of the season she's happily engaged, fans have known for quite some time she found her happily ever after.

Becca arguably deserved a happy ending more than anyone else in this franchise after Arie Luyendyk Jr. proposed marriage to her on The Bachelor's Season 22 finale only to dump her weeks later on-camera in order to reconcile with his runner-up, Lauren Burnham, whom he's currently engaged to.

Arie devastated Becca with cameras in her face after she fell madly in love with him and envisioned marrying him, but according to Chris, a similar situation played out with Becca, Garrett and Blake.

"What Arie fell into, Becca did too. She's in love with two men, Blake and Garrett, and she's making an impossible choice and it literally brings her to her knees," Chris revealed.

Becca also called The Bachelorette finale "intense," telling ET that viewers will experience a wide range of emotions -- from sadness to laughter -- on Monday night.

But according to Becca, all of the highs and lows of her time on the show were worth it.

The 28-year-old Minnesota publicist gushed of her current fiance, "We're ready to be done. We're ready to be us in public. I know it's going to be crazy when that moment comes, but it's going to be so worth it and so I'm going to be so excited for that day."
