Nick Viall is still thinking about one moment from his Bachelor season that was a little awkward and reveals which of his bachelorette's left him feeling a little uncomfortable!

In case you forgot, during Viall's season in 2017, Corinne Olympios took an opportunity to separate herself from the other ladies fighting for Viall's attention and decided to take her top off in the pool.

Nick Viall reveals which Bachelor moment was too much!

Nick Viall appeared on Monday's The Bachelor: The Greatest Seasons — Ever, and we got to learn more about which moment left him feeling awkward and uncomfortable! 

Blonde bombshell Corinne Olympios took an opportunity to stand out from the crowd, and thought taking her bathing suit top off was the best way to do it!

"It was really uncomfortable; it sucked," he said to Entertainment Tonight following the episode.

"I mean, I'm all sex-positive and all that stuff, but ... you're in a tough spot," Viall added. "I was literally 10 feet from the rest of the women, they were watching. And I also recognize that Corinne was taking a risk."

Viall then continued saying that he didn't react at the time because he didn't want Olympios to feel embarrassed.

"Whether I agreed with it or not, I didn't want her to feel stupid or vulnerable or judged," he said. "So you're really stuck between a rock and a hard place, so to speak. It wasn't my favourite moment."

Despite that one awkward moment, Viall says he had a lot of good memories being on the show, and Olympios eventually even made it to the final four.

"I'm proud, in a weird way, I took someone like Corinne far," he said. "I don't think in other seasons some of those women would have gone as far because I think sometimes, especially The Bachelor, feels like you're being judged. You play it safe, so to speak. I've never played it safe and I think that made for a really good season."

During that episode, Olympios joked that she made her father proud. 

"Dad would have been proud, even if I was naked," she said, holding her red rose.
