"I think it may in a few days," she added. "It's sad and it's unfortunate, because I just truly have loved my time here. I've loved this journey that I've been on, I've loved learning how to dance, I've loved meeting Artem and getting to know him and spending time with him."
"This place is amazing, and I'm just so grateful, but I'm glad that I got to experience all of this," she added.
For their performance on Monday, Bella and Chigvintsev danced a jive routine set to the classic tune "I Put a Spell on You," which earned them a 24 out of 30, tying them with Lachey and Chmerkovskiy for the lowest score of the night.
"[I've learned] that it's OK to be uncomfortable and go out of your comfort zone. When you think you can't, you totally can," Bella told ET. "It's OK to be silly and make fun of yourself, but as long as you're having fun, that's all that matters."
For Lachey, she admitted she's "going to miss the challenge" of the competition, but said that getting sent home isn't all bad.
"I was shocked, because I was so excited to get to the finals, potentially, and go to that level. But on the other hand, it's bittersweet because I get to snuggle with my kids until like, noon tomorrow," she said. "We're going to stay in PJs all day until we go to Disneyland."
"We went into some obstacles in the beginning," Chmerkovskiy admitted.
"Obstacles like I had two left feet!" Lachey chimed in. "He was like, 'You can't dance!' That was four weeks of work."
"But we found our rhythm and then we started to improve steadily. It was so obvious and that's so hard to do," Chmerkovskiy explained. "We put in work. We put in so much work. We put in constant, nonstop, massive giant effort."
For Halloween Night, Lachey and Chmerkovskiy got zombified for a spooky paso doble set to "Game of Survival" by Ruelle, which didn't really win over the judges, and could have been impeded by what looked like yet another wardrobe mishap.
