"I don't think it should be anybody from this season," Rachel, 33, told Us. "There's just so much cattiness going on. You don't know who to believe, you don't know what's true. I don't trust any of them!"
Hannah G. has stayed out of the drama for the most part, but Tayshia faced off against Caelynn and Cassie in a war of allegations.
Tayshia and her pal Kirpa Sudick, who previously got eliminated on The Bachelor, told Colton that Cassie and Caelynn were not ready to get engaged and didn't have the right intentions given they had allegedly discussed how they'd like to star on The Bachelorette.
"She said this, she said that, and usually, when you get down to the Top 4, it's drama-free... There's just so much going on. I don't like it! I can't see any of them being the next Bachelorette," Rachel admitted.
Rachel -- who is currently engaged to The Bachelorette's Season 13 winner, Bryan Abasolo -- suggested producers should instead take a look back at sincere contestants from seasons past.
"[Producers should] reach back and go pick somebody from another season," Rachel said.
"They're my friends, so it's nice!" Rachel said of Danielle, 33, and Kristina, 26.
"But I say that because I actually know them in real life, and I think they're two women that people want to see find love. You've seen their hearts broken multiple times in different ways, and they've both been very outspoken about that."
Danielle and Kristina both competed for Nick Viall, and then Kristina had her heart crushed by Dean Unglert on Bachelor in Paradise.
Danielle and Wells Adams appeared to begin a romance in Paradise, but their dynamic never blossomed into much more than a friendship.
Danielle then went on to date Big Brother alum Paulie Calafiore, but their relationship didn't work out because he wasn't ready for a serious commitment.
"I know them personally, away from the camera, and how much they really want to find their person. So I think they would both be great," Rachel insisted.
Colton is about to embark on his overnight Fantasy Suite dates in the next episode of The Bachelor on Monday, March 4. Hannah G., Cassie and Tayshia are still in the running for his heart and final rose.
