Last time we checked in on Teen Mom 2's Kailyn Lowry, she and her baby daddy, Jo Rivera, had just battled it out in court after getting into a physical altercation. But apparently, girlfriend wants to go at it for round two! This gal decides to go head-to-head with her ex-boyfriend for custody of Isaac, and no — they don't get into a rap battle, because please, Jo would win hands down. They don't call him Nerd in a Cool Kid's Body for nothing, guys!

So, why does Kailyn want to fight Jo for custody? Turns out this dude and his chintee are moving to New Jersey, and Kailyn is none too happy about the fact that he doesn't spend all his free time with Isaac. In fact, Jo even misses one of his scheduled days with Isaac to hang with his girlfriend Vee (aka Kailyn's public enemy no. 1)!

Kailyn decides to take Jo to court to revisit their arrangement, but unfortunately zero changes are made to the custody agreement, which means everyone got all dressed up in flared khaki pants for nothing. Yep, looks like the courts are siding with Jo for now, probably because they're huge fans of his music...

Sigh, at least Kailyn has her hunky boyfriend, Javi, to lean on. Call us crazy, but we're falling more and more in love with this guy as the weeks go on — and it looks like Kailyn and Isaac are right there with us!
