'Teen Mom 2' Leah Messer Blasts Corey, Praises Jeremy After Custody Battle Gets Worse!

Teen Mom 2 star Leah Messer is not done fighting with first ex-husband Corey Simms over their nasty custody battle where he got full custody of their twin girls. The MTV star took a jab at her baby daddy after her second ex-husband Jeremy Calvert was revealed to still be in his step-daughters' lives.

In posts on Instagram, Jeremy put up photos of his daughter Adalynn and step-daughter Aleeah playing together while at his other step-daughter Ali's singing recital. Check them out here:

After the adorable photo-op, Leah took to Twitter to post a meme that said, "Your ex is not your child's ex." She then took a jab at Corey for not having the best interest of little girls in mind.

Things have been getting ugly for a while between Leah and Corey ever since he accused her all of last season on the hit reality series of having a drug addiction. She went to rehab, but said it was for "anxiety and depression."

As MStars News reported, the most recent unpleasantness came from Leah reportedly accusing Corey and his wife Miranda of colluding with a teacher to fake her daughters' lateness records which led to her losing custody.

"Leah had all kinds of proof to shut them down," a source told Radar Online. "They admitted the records were inaccurate."

"Leah is convinced Corey and Miranda persuaded a school employee to mark them tardy," the source continued.

Do you think Leah and Corey's custody battle will get even worse?
