Earlier this week, we reported on the shocking / not-shocking news that Javi Marroquin and Lauren Comeau ended their engagement.

The breakup itself wasn't the biggest surprise of all time (breakups do happen in this world), but we were a bit taken aback by the circumstances.

Given that Javi and Lauren had welcomed a son, bought a house together, and gotten engaged, all in the past year, that development was a whole lot to digest on its own.

But it also came on the heels of a blowout fight at the couple's home in Dover, Delaware, and the situation has become even more bizarre in the ensuing days.

We now know that Javi called 911 on his sister, not on Lauren, as many outlets initially reported.

And while Lidia Marroquin was clearly involved in the altercation somehow, one insider tells The Hollywood Gossip exclusively that it all started because Javi got caught cheating on Lauren.

Jump into the gallery below for our inside information on this increasingly messy situation - and the predictably hilarious way he responded to being outed moments ago.

UPDATE: Thanks to The Ashley's Reality Roundup, we now know exactly why Javi called the cops, and we've also identified Javi's cheating partner.

This story gets more ridiculous by the moment, folks! Let's get into it ...
