Kailyn Lowry and Boyfriend Javi Marroquin Get in Twitter "War"

Oh, it's on! Super cute Teen Mom 2 couple Kailyn Lowry and Javi Marroquin "battled" each other on Twitter last night. But who came out on top?

It all started with a seemingly innocent tweet in Spanish: "Mi novio es el mas precioso em el mundo!" (Translation: My boyfriend is the most precious in the world.)

But while Kail is becoming fluent in Spanish, she didn't send out that love note!

"I love coming on here & seeing that my phone magically tweeted something for me," she said, adding, "If you're gona tweet from MY PHONE in SPANISH you should proofread for errors. @Javim9 I think you meant *DEL MUNDO*."

Oh snap! She's correcting Javi's Spanish? Javi wasn't going to take that lying down and declared, "Twitter war with @KailLowry ! Sorry for all the tweets in advance!"

He shot back, "Correcting my Spanish, but I helped you with your homework every night!"

Kailyn brushed him off. "There is nothing you can say to win this," she wrote.

After a few more rounds, Javi finally gave up.

"I'm the best girlfriend in the world. #iwin @Javim9 Better luck next time," Kailyn consoled him.

Although, let's face it, Javi ... you're never gonna win!
