Javi Marroquin is NOT pleased with Kailyn Lowry since they split, and he made that VERY clear to his Teen Mom 2 fan followers on Snapchat.

In his latest post, the father-of-one held up Kail's new memoir, Hustle & Heart — and chose to diss her with the caption, "I hate her, but I'm proud of her."

Yikes!

His ex seemingly clapped back to the nasty jab on Twitter.

"Karma got him," she wrote.

Perhaps Javi is not happy that Kailyn blamed his jealous and controlling nature for their breakup, which was confirmed in May. Both parties also accused each other of cheating during their four-year marriage.

The former couple has a two-year-old son together, Lincoln, and Kail is also the mother of Jo Rivera's six-year-old son, Isaac.
