Jenelle, 25, posted a live Instagram video in the early morning hours of Sunday, October 22, following the Saturday taping of the MTV reality series.
"I came here to do a live video... because of the sh-t that happened last night," said the former 16 & Pregnant star, according toUs Weekly.
"If you haven't heard, last night there was an article that, of course, comes out after I left, [saying] that they had to shut down production and Jenelle and David were acting crazy."
Jenelle was referring to her husband, David Eason, whom she married just last month.
Jenelle appeared to be addressing a report published by The Ashley's Reality Roundup, which claimed a blowout fight occurred backstage at the Teen Mom 2 reunion and temporarily shut down production. The website also reported that David pulled out a knife at a party for the cast in Los Angeles, CA.
When recalling the fight, Jenelle said her ex Nathan Griffith's mother Doris was rude to her, which resulted in a screaming match between Doris and David, prompting Nathan to "buck up" to him.
The reality TV star also claimed Nathan yelled at David, "Say what you want to me," to which her husband replied, "You're not worth it."
Jenelle dodged the knife allegations in her live video but explained that David made a little bit of a scene when he was denied beer at the party. She said, however, he just walked outside to cool down and popped some balloons on his way out.
As for Jenelle's own frustrations, she revealed that she was upset upon seeing Nathan's new girlfriend, Ashley Lanhart, hug her estranged mother, Barbara Evans, at the reunion.
Jenelle was also under the impression Ashley didn't want to be filmed for Teen Mom 2, Us reported, so she was taken aback by the cameras following her around.
When Jenelle asked Nathan's girlfriend about the film crew, Jenelle claimed that Ashley began to "cuss her out" and needed to be pinned against a wall before being asked to leave in front of Jenelle and Nathan's son Kaiser.

Nathan insisted on social media Sunday, however, that Jenelle was the real aggressor in all the drama.
Jenelle also reportedly had a conversation with Barbara that didn't go well.
Barbara allegedly told her daughter, "You are being abused, Jenelle, and you won't tell anybody. You're worse than you've ever been, even worse than when you were on drugs." Jenelle then reportedly snapped at her mom for hugging Ashley, saying, "Blood is thicker than water."
Jenelle and Barbara have struggled to maintain any type of relationship over the years considering Barbara has custody of her young son Jace.
Fellow Teen Mom 2 star Leah Messer seemingly proved there was tension on set by tweeting after the taping, "All I can say is WOW" with the hashtag #teenmom2reunion.
