Kailyn Lowry & Leah Messer's Costa Rican Vacation: What REALLY Went Down?

by at .  Updated at .

It's hard to think of anything less scandalous than a friendship developing between two longtime co-workers.

But when the colleagues in question are Kailyn Lowry and Leah Messer, a simple vacation is enough to fuel months of speculation.

Primarily, the rumors around the possibility that Lowry and Messer are dating.

It doesn't help that one of their co-workers -- *cough* Jenelle Evans *cough* -- has been providing grist for the mill by implying that these two are more than friends.

So what really happened when the moms set off for Costa Rica together?

Well, we finally found out on Tuesday's episode of Teen Mom 2.

Take a look:

1. Besties With Benefits?

Leah and Kail vacation together on a regular basis, and this has sparked romance rumors because ... they occasionally sport swimwear and take photos together?

3. Kail and the Kids

We're not really sure, to be honest. You'd think the fact that Kail and Leah frequently bring their kids on these excursions would be enough to quash rumors of an illicit affair, but apparently not.

Sure, some time had passed, and Leah seemed happy to be back on the market, but by all accounts, she thought Jason was The One, so the split must have stung at least a little.

Adding to the confusion is the fact that Leah had hooked up with ex-husband Jeremy Calvert just weeks before the Costa Rica trip.

10. Mixed Feelings

As for Kail, she'd be the first tell you that her personal life is pretty much always in disarray.

The life of a single mom of three is never easy. That's not to say Kail isn't up to the challenge -- but we're sure she could use a break from time to time.
