As for whether Soules might be interested in dating one of Viall's ex-girlfriends, he said, "You know, I don't know."
"I'd like to meet some of them. I think some of them are really cool," the Iowa farmer continued.
"But watching it, it's so hard to really learn, like -- I don't know. I guess I'm a little jaded to a certain extent -- but it's hard to [tell]. I think there's so much more to learn. I'd need to meet these girls in person."
One reason Soules has been hesitant to appear on Bachelor in Paradise?
"You know, I've gotten chubby!" he said with a big laugh. "My main concern is, like, those guys have abs! Sh-t!"
"The one thing a lot of people don't get to see is my hokey side," added the former Dancing with the Stars contestant.
"So I probably, I mean, I know I would have a ton of fun. But I don't know. If I can keep my T-shirt on when I'm in the ocean [then maybe]."
Soules proposed to Whitney Bischoff at the conclusion of his The Bachelor season, but they split seven months after he popped the question in an Iowa barn in 2014 and only two months after the March 2015 finale aired on ABC.
