Teen Mom fans concerned after Jenelle Evans' ex Nathan Griffith rants about 'aliens' and 'Jesus' on Instagram live

TEEN Mom fans were concerned after Jenelle Evans' ex Nathan Griffith ranted about "aliens" and "Jesus" on an Instagram live.

The former reality star took to social media to give a "lesson" on "mythical stories" referencing aliens and David and Goliath.

In the lengthy video, the ex TV star detailed his theories reciting from the bible before cutting the video short.

He captioned the post: "Unsolved Mysteries… SOLVED!

"Part I- paused due to weather."

Some fans voiced their concern for the father-of-two, with one asking: "Dude are you ok"

Another commented: "Lost your mind!"

"So lucky"

The video comes after Nathan posted a rare photo of his new girlfriend Keilyn in honor of her birthday calling himself "so lucky."

Last month, Nathan shared the photo on Instagram to gush about his new love interest Keilyn, 25.

The reality star shared a photo of his lady dressed in a matching floral two-piece set with a crop top and skirt component.

The blonde posed while holding a glass of champagne as the TV personality wrote: "How am I so lucky?!? #teamgriffith @keilynliznel."

Nathan also hopped on his Instagram stories to post a selfie with Keilyn as she sipped a fruity cocktail.

He helped light his girlfriend's birthday cake candles as they celebrated a quarter of a century.

Nathan's post came as a bit of a shock to fans after he recently broke up with his long-term girlfriend Lauren.

The Ashley's Reality Roundup revealed that “Nathan is not living in Florida anymore and has moved back to Tennessee to live with his mom [Doris].

“Ashley broke up with him," they claimed in early March.

After a tumultuous on-and-off relationship since 2017, a source revealed that the split was likely final, as “Nathan is seeing another girl already."

In October of 2020, Jenelle and Nathan finally "reached a custody agreement" for their son Kaiser after a nasty court battle.

TMZ revealed that the two will share custody of their son, along with Nathan's mom, Doris.

According to the court documents, Jenelle has primary custody while Nathan has been able to see him every other weekend.

However, in June the MTV star shared that for the first time, Kaiser will be spending the "entire summer" with his dad.

In a TikTok video, she told fans: “Time to drop Kaiser off with his dad for the summer.”

“And look at that purple hair!” as she had previously let the child dye his locks.

“I had to pack a bag because he’s gonna be gone for six weeks," she explained.

Later Jenelle claimed that her co-parenting with Nathan has seemingly been resolved, despite years of conflict.

“It’s so awesome that things can be so civil between all of us now to where we don’t argue at drop-offs and everyone gets along.

“Co-parenting done right," she insisted.
