Kailyn Lowry is reportedly taking her third baby daddy Chris Lopez to court.

According to a new report, the Teen Mom 2 star is reportedly banning her former boyfriend, who she was rumored to be reconciling with just weeks ago, from seeing their baby boy, Lux Russell, until after he acknowledges that he is, in fact, the father of the child.

“My guess is he won’t acknowledge paternity so she can’t file for child support,” an insider close to the reality star told Radar Online on October 9. “They give a form in the hospital, but he didn’t sign it.”

“Her lawyer drew something up and they are going through the court because he doesn’t have any rights to Lux without signing,” the insider continued. “He’s not seeing the baby right now for those reasons.”

After attempting to salvage their relationship, Lowry reportedly learned that Lopez was cheating on her and decided to give their son her last name instead of his.

“It took me so long to name the baby because I was trying to work with Chris to agree on the name. But we just couldn’t agree. Until we ended things [between us] for good and I decided I would just pick something I loved and he agreed to the first name prior to me deciding it would be the name for sure,” she explained to The Ashley's Reality Roundup.

In September, Lowry appeared to be hopeful about Lopez's role as a father to her third child.

“When he has the baby he does a really good job,” she told Radar. “He’s very hands-on when he is with him. I tell him all the time that I’m shocked and impressed. It’s not really what I expected. I never knew him around babies.”
