Olympios told ET previously that a guy needs to be "on point" to date her, noting that she likes older men. The oldest age the 25-year-old would date? 36. "I would never date someone younger than me," she said. "No younger guys. I don't even like it when a guy's only a year older than me, or even a few months. I don't know why; I need to feel protected, I think. I need to feel supported, protected, secure."

"I'm kind of picky when it comes to guys," she shared. "I have to know I'm being supported. I don't like guys that make jokes all the time...there's so many different kinds of guys, and I get so irritated so easily. It's something that, it's not them, it's me. You have to be super on point to date me."

One man she did say she finds attractive? Bachelor in Paradise's Chad Johnson, who she called "cute...tell him to text me!"

ET spoke with Johnson in February about his possible return to Paradise and whether he'd be interested in Olympios -- watch the video below!
