In the upcoming episode of ABC's season two of "Bachelor in Paradise," Lauren, one half of the Iaconetti sisters, decides she's rather go home and be a "mistress" than rough it out in paradise waiting for a rose from one of the eligible bachelors.

"I'm still confused about the sisters," Tenley Molzahn tells the camera. "Last night, Lauren was apparently having a meltdown and no one knows why."

The clip cuts to a scene where Iaconetti is talking to Tanner Tolbert and Dan Cox. She reveals the real reason why she hasn't tried to pursue anyone during her short stay in Mexico and why she's so eager to get back to the states.

"Do you have a boyfriend?" Tolbert asks.

"He's not my boyfriend, it's just someone that I'm super into," Iaconetti answers carefully.

The guys pry a little more and after a few more questions, she finally spits it out.

"He's not my boyfriend, I'm just like so in love with him I cant even do anything," she says. "I can't think about anything, I'm kind of a mistress."

Iaconetti explains that she's in love with a man back home who isn't married, but has a girlfriend and she mislabels herself as a "mistress." (FYI Iaconetti, the correct term for a woman who is involved with a man who has a girlfriend is 'sidechick,' according to Urban Dictionary.)

"She said 'I'm kind of a mistress' but he's not married so I just don't even think she knows what a mistress means," Dan says in his on-camera interview, and laughs. "But apparently she's dating guy who has a girlfriend. Seems healthy."
