It's the moment that all Teen Mom 2 fans have been waiting for! During last night's episode, Kailyn Lowry and her ex-husband, Javi Marroquin reunite for the first time since January. Click through for the biggest O-M-G moments from last night's episode!

Days before welcoming Javi back home, Kail took the boys to Puerto Rico with some of her friends to spend some time together.

Awkward! Despite not seeing each other since Javi left for his deployment, Kail and her ex still couldn't help but bicker a few minutes after he walked through the door. Javi asked if he could take Kail's son with Jo Rivera, Isaac, and the one child they share together, Lincoln, to day camp, but Kail denied him taking her car seats and told him to "get his own."

Terrifying! Leah Messer's home town suffered one of the worst floods in years, but luckily, her family remained safe.

Following her split with her second ex-husband, Jeremy Calvert, the two remained on good terms when it came to custody of their one daughter, Addie. After Jeremy returned home from work to help out with his family home, he took their 3-year-old daughter to Ohio without letting Leah know!

The summer is coming to an end! Jenelle Evans and her boyfriend, David Eason, took their kids to Orlando to spend some quality time together as a family while Kaiser spends time with his dad, Nathan Griffith.

But Jenelle didn't want her time with Jace to end! During their trip, her mom, Barbara, called and demanded that Jace comes back home to go to daycare. The feud began to escalate when Barbara told Jenelle, "When we go to court, we'll fight it out." Ouch!

And baby makes four! In the previous episode, Chelsea Houska revealed that she is expecting her second child, but her first with her new husband, Cole DeBoer.

So now, it's baby preparation! The married couple got to go see a doctor for an ultrasound AND they finally announced the exciting news for all of their fans following an adorable photo shoot.
