Kailyn Lowry is currently taking care of her newborn son, baby Lo, back home in Delaware. She's working with her ex-husband and her ex-boyfriend to care for her two other boys, Lincoln and Isaac. When she split from them, she worked out a custody agreement on both sides so she could see both of her sons. Despite never being married to Jo, the two worked out a great deal for Isaac. But when it comes to her ex-husband Javi Marroquin, it sounds like this "Teen Mom 2" star isn't playing fair. On "Teen Mom 2," Javi wants more time with his son and he also wants child support.

Perhaps Kailyn may wonder why she's working with him on these things, as he's already cozying up to his new co-star, Briana DeJesus.

According to a new tweet, Kailyn Lowry is now revealing that she thinks something is a complete joke and she posted about this right as Javi was making headlines for supposedly getting cozy with his new co-star in New York. Many fans have encouraged him to start dating Briana, as many feel they would make a great couple. They have already seen how Javi treated Isaac like his own son, so they strongly believe he could be a great role model to Briana's two daughters, Stella and Nova.

Cheating comes up again

When Kailyn Lowry tweeted about something is a joke, people quickly reminded her that she had been accused of cheating and that she may have been the reason why her marriage fell apart.

Of course, Kailyn wanted out of the relationship, but she probably didn't expect that Marroquin would pursue dating within the "Teen Mom 2" family.

One Twitter follower reminded Kailyn that she shouldn't be so quick to judge her ex-husband for moving on, as she was the one who filed for divorce and she had just given birth to her third son, a child by another man.

No word on whether Kailyn's tweet was actually about Marroquin.

His priorities

This past week, Javi was seen hanging out with celebrities at an OK! Magazine party. He took pictures with various famous personalities and even squeeze in a picture of himself with Briana DeJesus, the newest cast member of "Teen Mom 2." While his priorities are his child and his health, it is possible that he wants to find the right woman for him and his child.

He has tried dating since his split, but it didn't go well. Within weeks, there were rumors of cheating and lying.

What do you think Kailyn Lowry meant with her tweet that something is a joke? How do you think she would feel if Javi did start dating their "Teen Mom 2" co-star?
