The Ultimatum star Lisa Horne sparks fury from viewers after HITTING her boyfriend in dramatic on-air fight over his flirting – before sensationally QUITTING Netflix dating show after discovering she’s pregnant

Ultimatum star Lisa Horne has shocked Netflix viewers around the world after she was filmed punching her boyfriend Brian Okoye after he flirted with another woman – before finding out she was ‘pregnant’ and sensationally calling it quits with the show.

The explosive new season, which sees couples break up and move in with a new partner after being given ultimatums, kicked off Wednesday and was immediately thrown into chaos when the 31-year-old physically lashed out at her other half.

The drama unfolded at the end of episode one, when a frustrated Lisa witnessed 28-year-old Brian attack fellow contestant Riah.

Lisa unleashed her anger at the start of the second episode and was seen pushing Brian away from the other contestants with her hand in front of his face as they gathered in a restaurant, the scenes sending a wave of anger from the viewers.

They then released their argument, where she yelled at him repeatedly, “What are you learning from her? This bitch doesn’t dare you.’

‘What are you talking about?’ replied Brian. “Are you mad because I’m having a conversation?”

Their bitter feud ended when Lisa demanded to go home and screamed that her relationship was over. “We’re done,” she said. “F*** marriage, f*** The Ultimatum, f*** you.”

But the drama was far from over and before the credits came on the episode, co-host Nick Lachey revealed to the cast that Lisa and Brian had dropped out of the experiment because she was pregnant.

Speaking to the remaining cast members as they gathered around a dining room table, he said, “You probably noticed the two chairs that are empty at the far end of the table.” Lisa and Brian have decided to withdraw from the experience.

“We invited them to come here and tell you the news yourself, but they declined. Lisa came to us and told us that she had taken a pregnancy test and it was positive.’

Lisa talked about her amazing pregnancy in episode three and admitted she was “nervous” about breaking the news to her partner.

“Honestly, I’m surprised,” Brian replied. ‘Very surprised. Are you 100% pregnant?’

“I’m at 99.99 percent,” she confirmed, prompting him to get excited: “This is a lot, but I’m happy. I am super happy. I am here for you. I love you.’

But angry Ultimatum viewers have called out Netflix for “turning a blind eye” to Lisa’s behavior and have questioned why she wasn’t immediately cut from the show.

“She completely beat him, and no one blinked,” one wrote. “Imagine a man doing that. If I were Brian, I’d actually want to see a positive pregnancy test. The whole situation is uncertain.’

“How on earth can The Ultimatum accept physical violence?” another questioned.

A third added: “I really think they should have been removed from the show immediately when she hit him. That should be a line that once crossed, male or female, they’re kicked off, even if it’s unfair to the one hit.’

Ignoring the controversy, Lisa said she “put her heart on the line” in The Ultimatum

DailyMail.com has reached out to Netflix for comment.

While Lisa has yet to discuss the controversial scenes, she told her 19,000 followers on Instagram that she “put her heart on the line” on the Netflix series.

In a post on her social media profile, she wrote: “I put my heart on the line…was it worth it? The Ultimatum: Marry or Move Season 2 is now on Netflix.”

Unsurprisingly, the upload was flooded with criticism from viewers, with one comment: “So you’re just not going to talk about how you punched that guy in the face?”

“The way you shoved him in the face was horrible to watch,” said another. “Toxic as hell.”

The shocking scenes come just weeks after the reality show Below Deck Down Under was embroiled in a sexual misconduct scandal when ex-cast member Luke Jones climbed into the bed of Margot Sisson, who was fast asleep in her underwear, “without permission.”

Luke was dismissed from the boat by Captain Jason Chambers along with second stew Laura Bileskalne, who insisted her colleague was not to blame and was released for showing “little respect and empathy” towards Margot.
