Clutch your pearls, Teen Mom 2 fans! It looks like Kailyn Lowry is about to take a huge step in her custody battle against the rapping superstar known as Nerd In A Cool Kid's Body (aka her baby daddy, Jo Rivera).

Up until recently, Kailyn and Jo shared time with their son, Isaac (with Kailyn having primary custody), but times are a-changin' now that Kailyn's married to her Air Man hubby, Javi Marroquin. Kailyn and Javi just bought a house near Javi's Air Force base (rumored to be in Delaware), which means Isaac may be leaving his home state of Pennsylvania. Unfortunately, Javi's base is several hours away from Jo's current pad in New Jersey, so Kailyn and NICKB are going to have to re-work their custody agreement.

Let the drama begin!

Jo's made it clear that he has no intention of letting Kailyn acquire full custody of Isaac, but it looks like she's attempting to do just that.

"Today is a HUGE day for Isaac and myself," she tweeted on August 5. "A decision could be made today that will change the rest of our lives. Hoping for what's best!"

Fans immediately jumped on Kailyn for taking Isaac away from his father, but she assured everyone that Jo will always be part of her son's life.

"I wouldn't ever take Isaac away from his dad like that! ;) But it's kind of like that," she explained.

Do you think Kailyn should get full custody of Isaac? Check back in with Wetpaint Entertainment for the outcome of this gal's battle with Jo, and make sure to wish her good luck on Twitter!
