Let's get ready to rumble? Jenelle Evans' ex Nathan Griffith has made it pretty obvious he is not a fan of her husband David Eason — but now Nathan, who shares son Kaiser with the Teen Mom 2 star, is ready to fight it out with his nemesis.

"DAVID! I begged @mtv to host a mma fight for us and because of you they can’t now. Fighting words?!?!? Please, I would love to. I want a perfectly legal, conscience decision (on your part) and good fight," he tweeted. "I know if it’s in a ring, the moment you come at me… Imma clean that clock of yours and then maybe you can think straight!" It wasn't long before Leah Messer's baby daddy Jeremy Calvert, who has also feuded with David in the past, got involved. Watch the video above for his epic response!

Currently, Nathan is battling with Jenelle over custody of their three-year-old son, after accusing David of abusing Kaiser. "He told me David punched him one time," Nathan said on the show. "It does seem he has tendencies to be a violent person." This prompted Nathan's mom to file for emergency custody — behind Jenelle's back. "She said she was worried about the bruises he comes over her house with. I told my lawyer Kaiser came home with finger bruises on his butt from being spanked," the mother-of-three explained.

Jenelle also claimed David was just play fighting with Kaiser. "He doesn't touch the kids like that. David punches Kaiser in the face. He plays around! That's what Kaiser means," she added. "She's taking this out of proportion. Everything is fine and everyone else thinks it's not."

And Jeremy also has reasons to want to see a fight between Nathan and David. He recently called out the fired reality star for his homophobic comments on Twitter. "You say you don't know how to use Twitter but, goddamit, you use it an awful lot for not knowing how to use it," he said on Instagram Live before encouraging Nathan to fight for custody. "If Nathan don't [sic] try to get his kid, I don't know what to tell that dude. I would have already been in court… even if I had to empty my savings account out, I'd go broke."
