Corinne Olympios provides a lot of laughs for The Bachelor fans, but host Chris Harrison suggests her relationship with Nick Viall is no joke.

"Corinne is a serious candidate," Harrison told Us Weekly.

But Harrison said Olympios has one thing "in common" with the other remaining ladies -- Kristina Schulman, Raven Gates, Rachel Lindsay, Danielle Maltby, and Vanessa Grimaldi.

"One thing that you'll notice as the cream starts rising to the top, so to speak, [is] they're all very strong, independent, intelligent women who own who they are," Harrison said. "They may do that in different ways."

While some of the women, like Grimaldi, speak their minds, Olympios leads with her sexuality and has absolutely no reservations. The Miami, FL, native already flashed Viall her breasts and asked him to lick whipped cream off her chest, and previews reveal Olympios will attempt to have sex with the Bachelor prior to his round of Fantasy Suite dates.

"I think people kind of laugh at Corinne," the host noted, "but she is pretty smart, and she's been playing this very well, and she knows what she wants."

Harrison added of the polarizing bachelorette, "Say what you will about her, that's attractive to Nick."

Viall has admitted in recent weeks he appreciates Olympios' confidence and desire to keep things light, flirty and fun. The 36-year-old software salesman also loves an aggressive girl who goes after what she wants.

"It may not be attractive to everybody, but he's drawn to that," Harrison said of Viall, "and I think that all of those girls that are rising to the top definitely have that 'it' factor that he finds appealing."

Viall's turn-ons are obvious considering he fell for former Bachelorettes Andi Dorfman and Kaitlyn Bristowe, who both had strong personalities. Dorfman was a feisty assistant district attorney at the time they dated, and Bristowe has a wild and loud sense of humor. On the contrary, Viall failed to find love with the sweet and seemingly soft-spoken Jennifer Saviano on Season 3 of Bachelor in Paradise.

Olympios is "open and honest," noted Harrison, adding that the other women may "just be a little more subtle. One thing you will not ever say about Corinne is that she's subtle."
