And the plot thickens.

In PEOPLE’s exclusive sneak peek at Tuesday’s episode ofSiesta Key,Alex Kompothecrascomes clean to his girlfriend Alyssa Salerno — thefuture mother of child— about where things really stand with his exJuliette Porter.

“So I have something that is not a huge deal,” he begins. “But I feel like you should hear it from me before you hear it from someone else. A few weeks ago, I was talking to Juliette. It started off small, and then one night I ended up staying on phone with her for a really long period of time — like, six hours.”

“I just felt bad, like, her whole perspective on this breakup —” he continues, but Alyssa cuts him off.

“Wait, wait, wait,” she says, eyebrows raised. “Why am I just know hearing about all of this?”

As it turns out, it’s because Juliette is on her way to the very party the couple is currently at.

“Because she’s coming,” Alex says. “I would rather you hear it from me than from her. The last thing I need is for her to run up to you and give her side of the story before I tell you.”

“So it takes her coming here for you tell me this?” Alyssa demands. “Does that not sound really f—ing sketchy? That you’re like, ‘Oh s—, I need go up to Alyssa and tell her this.’ That’s kind of bulls—.”

Alex insists he’s “not lying,” and simply “didn’t think it was a big deal.”

“How is it not a big deal?” Alyssa fires back. “Your ex calling you and you’re talking for six hours?”

“I just want you to know,” she warns. “I’m not a dumba–.”

“Weird how he cheated on her with me several months ago but ok,” she wrote in a since-deleted comment on The Morning Toast’sInstagram postabout the announcement. Alex has not publicly addressed the allegation.
