Fans have been dying to know if the chemistry is still there between Kailyn Lowry and her ex Chris Lopez. With their son Lux's first birthday right around the corner, the Teen Mom 2 star revealed the status of their hot and cold relationship during an interview on July 11.

"We are getting along and doing everything we can to be there for our son," Kailyn told OKMagazine.com. The reality star has been very open about how their split broke her heart, but it looks like they're putting their differences aside to co-parent Lux cordially. Only one day ago, Kailyn hinted that she was going to be celebrating her son's b-day with her former flame.

"Hiiiiii followers," Kailyn wrote via Twitter. "So I was going to have a Coco theme party for Lux, but Chris and I decided to change it last minute. I have a ton of fiesta/Coco theme birthday stuff unopened and unused. If you could use it tweet me!" Some fans were concerned about her playing nice with Chris, especially considering their rocky past together. Kail fell head over heels for Chris shortly after her split from her ex-husband Javi Marroquin, and it wasn't long after that she got pregnant with their son.

"I believe Lux's dad was my first true love…I know, weird, when I had two kids with two other people," Kailyn revealed about her third baby daddy during a Q&A via her blog on June 22. "But this is my life. This was my first REAL heartbreak, where I loved someone and was IN love with someone. And I felt so abandoned during such a vulnerable time." Even though the exes aren't rekindling their romance, we're glad to see them putting on a united front for the sake of making their little one happy!
