"Jessica and I, we have a past. We dated in the past. But going on the show, we weren't together. That's basically it," he told ET Canada in a Monday interview.
The 26-year-old entertainment wrestler from Toronto, Ontario was eliminated by Fedotowsky during Monday night's The Bachelorette broadcast after Spillas told her over the phone that the two were dating.
Fedotowsky ousted Rego after confronting him in front of the six other remaining bachelors -- causing Rego to initially walk away and decline to discuss the allegations.
"She decided to confront me in front of all the guys, which I didn't appreciate," he told ET Canada.
"I kind of felt like I wasn't able to get my word out. To be honest with you, I didn't want to be a part of a huge scandal. I didn't want to be in the middle of this all. So I walked out."
Spillas also told Fedotowsky that the only reason she decided to out Rego was because she recently learned he had also been dating another woman named Kimberly Kerekes -- meaning he allegedly had two at-home girlfriends during filming.
While Rego described Spillas as "somebody that I always wanted in my life cause she's a great person," he said that is no longer the case because of the way she contacted Fedotowsky.
"Unfortunately now due to the fact of all this happening and seeing her true nature and true intent I really don't want to continue any type of relationship with her," he told ET Canada, People reported.
Rego was also asked about a text message exchange Spillas shared with ET Canada in which Rego had told Spillas he wanted to marry her and proclaimed that she meant "the world" to him shortly before leaving for The Bachelorette.
"I broke my foot just two weeks prior to going onto the show. With Jessica, I'll admit, she helped me out through that time. She was fantastic and literally kind of painted the perfect picture of what I wanted my wife to be like," he explained to ET Canada before adding he was clear to Spillas that they were not dating.
"I explained to her, 'You're single. You can go ahead and date any guy you want. I know I'm single.' So when a guy tells a girl that, it's kind of a little bit obvious that both parties are single."
Still, Rego claims Spillas was looking to get back together once she learned he was going on The Bachelorette.
"All of a sudden, she finds out I'm going on the show and she pops up in November being like, 'Hey, I miss you. I want to be with you.'" he told ET Canada.
"That's where my emotions were played with."
Despite accusations from both Spillas and Kerekes that he was only on the show to promote himself as an entertainment wrestler, Rego said his The Bacheloretteintentions were true.
"It's difficult to say, 'You know what, I'm going to fall head over heals for somebody. But I was definitely open to that idea," he told ET Canada.
While Rego also previously stated that he would "love" to beThe Bachelor's next star, he said that is a role he "definitely" does not want anymore.
"No more reality TV," he told ET Canada, according to People. "This has been such a rough experience, like it's kind of scared me away from doing anything. It's not fun having you're name dragged through the mud." Instead, Rego said he'd like to enforce the law.
"In the next year or so I'm actually looking to be a police officer," he told ET Canada, People reported. "I'm slowly studying it... that's something I truly am passionate about and I definitely want to get into."
