Jenelle Evans has not seen her son, Kaiser, outside of a court-supervised visitation center in over a month, but on Saturday she and her husband David Eason celebrated Kaiser’s birthday alongside her ex Nathan Griffith, estranged mother Barbara Evans and Kaiser’s half-siblings Jace and Ensley.

No….we have not just entered The Twilight Zone.

As she was leaving court on Friday, Jenelle told a reporter for Radar Online that she would be celebrating Kaiser’s birthday with him the next day, but Teen Mom 2 fans were skeptical, given that Jenelle (and David) are currently in the middle of a nasty court battle to regain custody of any of their kids. However, it turns out that Jenelle was actually telling the truth, and she did, indeed, celebrate her son’s birthday with him, and even posted photos to her social media accounts as proof.

“Can’t believe you are 5 already!” Jenelle captioned a series of birthday party photos posted on Saturday. “You might be getting older but you’re still my baby.”

Barbara also posted pictures of the festivities, even pointing out in the caption of one Instagram photo how rare it was that David and Nathan were around each other (and it didn’t end with anyone going to the slammer.)

“Omg Nathan on left David on right today at Kaiser’s Birthday Party.Finally all getting along,” Barbara wrote.

While many fans who have been following Jenelle and David’s battle to regain custody were stunned, and some even upset, that David and Jenelle attended the party, Nathan took to Twitter to explain his reasoning for allowing them to be there.

“My children will always come first regardless of my own personal feelings,” Nathan tweeted. “I will always want the best for my children. Happy Birthday Kaiser and I’m so glad you could spend it with FAMILY and friends! # WWJD # TeamGriffith # Lovemore # hateless

Nathan, who was threatened online just days ago by David, explained that his girlfriend, Ashley Landhart, suggested he invite Jenelle and David for Kaiser’s sake.

“Actually… Ash and I were talking about Kaiser’s birthday and Ashley suggest[ed] that it would be nice to invite them,” Nathan wrote. “I brought up the proposition to my lawyer and he said ‘YES!’ At the end of court the lawyers got together and agree[d] to the idea.”

The Ashley hears that no court or CPS worker was supervising David and Jenelle at the party, which took place at the home of Nathan’s mom, Doris Davidson. (It did not take place at Jenelle and David’s home on The Land as some fans thought.) It was also OK’d by the court.

Nathan told worried fans that David and Jenelle were on their best behavior at the party.

“David [conducted] himself very [professionally]. Honestly, this whole birthday party was simple but absolutely a wonderful experience,” Nathan wrote, insinuating that David wasn’t left alone with the kids.

“What is he going to do with 8 adults there and 10 children? Besides, I want to promote a path that brings positivity to everyone. Vengeance is the the Lord’s, not mine,” he wrote.

While Barbara allowed Ensley and Jace to be at the party, David’s son Kaden and daughter Maryssa were not there.

In photos posted from the party, Kaiser— who was turning five— looks thrilled.

The festivities will be short-lived, however, as Jenelle and David will return to the courtroom on Monday afternoon to continue their fight for custody.
