On Monday's episode of The Bachelorette, Ali Fedotowsky angrily confronts Justin "Rated R" Rego after learning that he has a girlfriend.

"It's unspeakable what you've done!" she fumes in the above clip. "I came here to find a husband, and you're f****** with that?!"

When Rego gets up to leave, Fedotowsky, 25, digs into him even further.

"You're seriously going to walk away from me?" she cries. "This is how you want to be perceived? You're gonna regret this!"

The episode takes an even juicier twist when Rego's girlfriend Jessica calls Fedotowsky to tell her that they both have been played.

"He assured me that when he got back, we'd start our plans to get married. And I believed him," says Jessica, adding that Rego told her he was just going on the ABC show solely to further his wrestling career. "He said going on the show would benefit the both of us. He wanted to get into the top three because he'd be well known."

Watch Fedotowsky and Rego's full confrontation when The Bachelorette airs Monday at 8 p.m./ET on ABC.
