Kailyn Lowry welcomed her third son, Lux Russell, in August of last year after a dramatic split from her third Baby Daddy, Chris Lopez, several months prior. As "Teen Mom 2" fans will recall, Lowry and Lopez dated briefly after her breakup with Javi Marroquin but split soon after the reality star learned she was expecting Lopez's child. Ever since, the former couple has been majorly at odds as they attempt to co-parent their young son.

In addition to dissing Lopez on Twitter and on episodes of "Teen Mom 2," Lowry also took legal action to have the name of their eight-month-old son from Lux Russell Lopez to Lux Russell Lowry.

In what appears to have been the biggest diss of all, Lowry requested her ex-boyfriend's last name be removed from the child's moniker and on April 11, her request was granted by the Kent County Court in Delaware. Radar Online confirmed the news on April 16.

Kailyn and Chris were recently involved in an Instagram feud

According to Radar Online, Kailyn Lowry and Chris Lopez came to blows on Instagram last month after Lopez shared a photo of himself and their child. In response to the image, Lowry seemingly called out Lopez for pretending to be a good parent [VIDEO] on social media to safe face. “Don’t be an Instagram parent,” she advised.

A short time later, Chris Lopez fired back at Kailyn Lowry. “But a person who literally made a living off of putting their kids on TV and social media, but hey who am I to talk,” he wrote.

As fans well know, Lowry has been starring on reality television for nearly a decade after becoming a teenage mother eight years ago. Since then, she has been marketing herself online and further exposing her life through books and her podcast, "Coffee Convos."

Kailyn Lowry has two older children from her other baby daddies

In addition to her eight-month-old son Lux Russell, Lowry also shares two older children, including eight-year-old Isaac and four-year-old Lincoln, with her ex-boyfriend, Jo Rivera, and ex-husband [VIDEO], Javi Marroquin, respectively. As fans well know, Lowry has faced a lot of backlash due to the number of baby daddies she has but that hasn't stopped her from considering a fourth child.
