'Teen Mom 2' Star Kailyn Lowry and Ex-Husband Javi Marroquin Are Beefing (Again)

Up until now, Teen Mom 2 star Kailyn Lowry and her ex-husband Javi Marroquin have maintained a solid co-parenting relationship. However, the mom of three says things between them have started to go left based on a number of factors.

Kailyn and Javi, who share a 4-year-old son named Lincoln, are currently on the TV series Marriage Bootcamp. During last week's episode, the exes got into a spat over their child support arrangement. After seeing the way things played out on screen, old feelings started to bubble up and before you know it, the reality stars exchanged some shady tweets.

“Someone’s bitter and can’t move on from s—t that happened almost two years ago #yesterdayspaper #MarriageBootCamp and #moveon,” Marroquin tweeted. "Have more important things to worry about right now than a past relationship that’s dead to me. Lincoln is the only thing keeping it alive. Which I’m blessed for don’t get me wrong. But him, that’s it."

Kailyn responded simply to say that she's disappointed they couldn't continue a civil relationship. “Wow, disappointed in yourself that you let OTHERS influence how you treat the mother of your child, yet here we are again,” Lowry tweeted in response.

Today, the Teen Mom star went into further detail with Us Weekly, saying she's disappointed that things have taken a petty turn with her child's father. “Javi and I got to a really good place by early Fall and it’s unfortunate that things have changed so much to the degree that it’s affecting our ability to coparent,” Lowry, she told the magazine exclusively. “However, I’m not going to let this stop me. I’ll continue to be respectful to the father of my child and keep working at my career."

Aside from the personal issues between them, Kailyn and Javi are each juggling romantic relationships of their own. Lowry revealed in November that she currently has a girlfriend, and Javi is dating fellow Teen Mom star Briana DeJesus. “She’s what’s keeping me together right now,” Javi told Radar Online of his relationship with Briana.

Whew! This cast has more drama than Young & The Restless. Hopefully these two can work based their issues and get back on friendly terms again.

Javi and Kailyn should call up the Harris family for some co-parenting advice! T.I. and Tiny may have gone their separate ways, but their co-parenting is still going strong.
