'The Ultimatum' star Lisa says she doesn't regret calling Riah a 'Hooters bitch'

• "The Ultimatum" reunion episode aired Wednesday, featuring updates from season two's couples.
• Lisa Horne revealed she had her baby, and said she didn't regret calling Riah a "Hooters bitch."

Jelisa "Lisa" Horne and Brian Okoye's relationship was only featured on a few episodes of Netflix's "The Ultimatum: Marry or Move On" season two, but the couple definitely garnered some attention for their intense fight during the cocktail party in episode two, and the subsequent reveal that Lisa was pregnant.

In the reunion episode for season two, which premiered Wednesday, Lisa weighed in on her controversial actions from earlier in the season — including calling fellow cast member Riah a "Hooters bitch" and implying she was immature after seeing Riah speaking with Brian.

"I don't regret what I said. Because I didn't base my assumption off of her job, I based it off of how she was acting during this process," Lisa told "The Ultimatum" hosts Nick and Vanessa Lachey during the reunion.

"For me, I felt like if you are in love with someone that you came here with, you're not seeing someone and thinking 'Oh my god, he's hot. He makes me hot,'" Lisa explained.

The new mother also said that Riah's willingness to explore a connection with Brian made Lisa question if she was really interested in fixing her relationship with her own original partner, Trey, or if she was focusing on ways to get with Brian.

"I just felt at the time, I didn't feel like she was that into the person she came with. I felt like Trey was a great catch… he's ready to marry," Lisa said, adding that "at the time, I felt like she doesn't love him."

She went on to share that she felt Riah crossed a line with her by pursuing Brian.

According to Lisa, her reaction the night of the cocktail party was what prompted her to take a pregnancy test, since she felt something was amiss.

"Not that it excuses my behavior at all, but it definitely made me realize that this is why I'm acting psycho," she said of her decision to take the test.

And seemingly alluding to her striking Brian across the face, Lisa said she regretted that moment.

"I was very remorseful for doing that. It wasn't okay. Even the hormones, regardless of being pregnant, that doesn't excuse it," she said.

She also confirmed that she and Brian recently welcomed a healthy baby boy named Mason.

"The Ultimatum: Marry or Move On" season two finale and reunion episodes are currently streaming on Netflix.
