Epic Diss! Javi Marroquin Accuses Ex Kailyn Lowry Of 'Opening Legs' To Another Man

Teen Mom 2 is back with even more drama, fights and breakdowns than ever before! In a trailer for the upcoming season, Javi Marroquin delivers an epic diss to estranged wife Kailyn Lowry, while Leah Messer suffers a devastating blow.

In the video, Lowry tells her husband that she is officially ending their nearly 4-year marriage.

"We're getting divorced," she told Marroquin when he returned home from Air Force deployment. "Period. Point blank. It's not like we were this happy couple."

Marroquin angrily responded, "You never think about anyone else. You don't think about me, you don't think about your two boys. You're going to open your legs to some guy that's not a big f*****g deal?"

Although Messer seems to be improving after her rehab stint for stress and depression, she broke down when discussing her daughter Ali's medical issues.

"Knowing there is something wrong with this baby that I love so much," she said of her daughter, who suffers from muscular dystrophy.

As for Jenelle Evans, she continues to fight for custody with her mother Barbara over her son Jace.

"You do not want to give me my son back so I do not want to film with you ever again in my f*****g life," she screamed at her mother, as Babs fired back, "If I get custody then you will have limited visitation!"

Evans also denied her pregnancy in the trailer, as her mother caught her in a lie by reading a police report from a car accident Evans was involved in.

"The passenger is at least 10 weeks pregnant," she read.

But the trailer wasn't all drama, as Chelsea Houska revealed she's expecting a child with now-husband Cole DeBoer.

Unfortunately for Houska, who is due in February, her bad boy baby daddy Adam Lind overshadowed the joy.

For their daughter's 7th birthday, she explained how Aubree didn't receive a "phone call, nothing" from Lind.

The season premiere of Teen Mom 2 airs Monday, January 2 at 9/8c on MTV.
