'Teen Mom 2' Leah Messer Called "B**ch" & "Dumb Ass" By Jeremy Calvert With Big Sean Song!

Teen Mom 2 star Leah Messer is going through hell with her impending divorce to Jeremy Calvert and a nasty custody battle while she deals with her alleged drug addiction. Now, her husband is going even lower by posting a song seemingly calling the MTV star a "dumb ass" and "b**ch"!

In a shocking post on Twitter, the reality dad put up the very explicit breakup song "I Don't F**k With You" by rapper Big Sean. Many have speculated the tune is about the end of the hip-hop superstar's relationship with Glee star, Naya Rivera.

The graphic lyrics to the track include, "I don't f**k with you// You little stupid ass b**ch, I ain't f**kin' with you// You little dumb ass b**ch, I ain't f**kin' with you// I got a million trillion things I'd rather f**kin' do// Than to be f**kin' with you// Little stupid ass, I don't give a f**k// I don't give a f**k, I don't I don't I don't give a f**k// B**ch I don't give a f**k about you or anything that you do// Don't give a f**k about you or anything that you do."

Things have really deteriorated for the MTV couple since Jeremy served his reality star wife with divorce papers. As MStars News reported, a custody battle is brewing between the West Virginia natives over their daughter Adalynn, especially since Leah may have to go to rehab for abusing pills.

"She's confessed to Jeremy that she has a problem, and knows she has no other choice than to go to rehab immediately," a source told In Touch Weekly, via Radar Online. "MTV would foot the bill and force Leah into rehab because the network loves her. They last thing they want to see is her going down the same dark path that Amber Portwood and Jenelle Evans did."

"[Jeremy] is going to be seeking primary custody," the source continued.

Do you think Jeremy went below the belt posting the song about Leah?
