The drama never stops with this guy! Nathan Griffith took to Twitter on Monday, July 24, to slam his ex Jenelle Evans. In his online tirade against the 16 and Pregnant alum, 25, Nathan also suggested that her fiancé, David Eason, was on drugs on the most recent episode of Teen Mom 2.

As TM2 viewers saw on Monday night, Nathan faced off with Jenelle in court as they fought over custody of their three-year-old son, Kaiser. The Read Between the Lines author went to mediation with Nathan (who was allegedly dealing with a drinking problem at the time) to change their custody agreement so the fitness enthusiast only sees Kaiser every other weekend, and he must be supervised by his parents whenever he’s with their child.

Much to Nathan’s dismay, Jenelle got exactly what she asked for. “Brat got everything she wants, like always,” Nathan said of the approved agreement. His fury spilled over on social media moments after the tense moment aired on TV.

“Unless you’re trying to hide something, I didn’t know you had to protect your eyes from the UV rays inside… ?” Nathan tweeted, clearly referencing the sunglasses David wore indoors when he accompanied Jenelle to court.

The personal trainer’s girlfriend, Ashley, chimed in with a tweet of her own, insinuating that David may have worn the shades to mask his being under the influence. “I think I would recognize if my boyfriend had an alcohol problem,” she wrote. “I do recognize when sketchy people wear sunglasses inside tho ?.”

Jenelle and David have yet to directly address Nathan and Ashley’s tweets. The couple’s insults come just days after Nathan dragged Jenelle for her parenting skills in a series of heated tweets after Kaiser was seen behaving badly on an episode of TM2.

“He can definitely be a handful but it’s not his fault. I think a little love, structure, and attention can go a long way in a child’s life,” he wrote, adding that he has “discussed these issues with David and Jenelle.”

Jenelle is also mom to Jace, 7, with ex Andrew Lewis, and seven-month-old daughter Ensley with David. Teen Mom 2 airs on MTV Mondays at 9 p.m. EST on MTV.
