Nick Viall and Vanessa Grimaldi's romance isn't authentic -- at least according to The Bachelor villain Corinne Olympios.

The blonde beauty from Miami, FL talked to SiriusXM Music Hits 1 about The Bachelor's newest couple, whose love story continues to unfold now that their engagement is public knowledge and Nick is competing on Dancing with the Stars with Vanessa's support.

"I have a lot of respect for both of them, I just personally -- not saying anything bad about either of them -- I just personally don't think that they're compatible," Corinne told the satellite radio channel.

Corinne competed against Vanessa for Nick's heart on The Bachelor's 21st season but was sent home after her hometown date during which she confessed her love for the 36-year-old former software salesman.

After Corinne questioned Nick's compatibility with the feisty Canadian teacher, one of the radio hosts offered up his two cents on the topic: "I think they're both in it just for publicity and as soon as the publicity runs out, they're going to breakup."

Corinne hesitated to respond but then confessed to the radio hosts, "I think that you're on point. They're so phony with each other."

"It just sucks, because they're both really real people separately," Corinne continued, "but whenever they were together looking at them -- like, I lived with Vanessa and dated Nick -- that's not how either one of them really are. And I'm like, 'What are you guys doing?'"

Corinne enjoyed expressing her sexuality on The Bachelor and was always unapologetically herself. She often rubbed her fellow bachelorettes the wrong way and was all fans seemed to talk about as Nick's season of the show was airing on ABC earlier this year.

While it's unclear whether Corinne will land her own reality TV spinoff or appear on the upcoming fourth season of Bachelor in Paradise, she confirmed she will be making a cameo on Rachel Lindsay's The Bachelorette edition, which premieres May 22 at 9PM ET/PT on ABC.

"I filmed an episode with her and I met some of the guys she's dating," noted Corinne. "[They're] cute, yes. We're off to a good start."

While Corinne revealed Rachel was a little anxious during filming, the blonde beauty insisted the Bachelorette will charm both her suitors and viewers at home.

"It's only natural that she'd be nervous -- I would be nervous," Corinne said. "She's just so endearing and bubbly and inviting that I don't think people will pay attention to it."
