'Teen Mom 2' Jenelle Evans Slams Nathan Griffith In Twitter Fight: Says Ex Is On "Steroids!"

Teen Mom 2 star Jenelle Evans has started a new life with current boyfriend David Eason, but she is still taking time blasting her ex-fiancé Nathan Griffith. Even though the former reality couple shares a son, Kaiser, and are in the middle of a custody battle, they are still going back and forth with the low blows. This time, the MTV star accused her baby daddy of allegedly being on steroids!

In a nasty exchange on Twitter, the military dad threw the first punch by posting a dig about who he regrets dating.

"Note to self* 'don't date anyone if your previous girlfriend is still pregnant with your child!'" Nathan wrote.

Well... Jenelle wasn't going to take this lying down and catapulted her own verbal assault to her ex by tweeting, "Note to self: don't date anyone on steroids." Ouch!

Just earlier, the North Carolina mom retweeted a message from a fan about Nathan's verbal abuse towards her.

"Wow just watch teen mom2.. The way Nathan speaks to you is awful. Guys trying to mess with your head and break you," Twitter fan Gemma Douglas posted.

This is just the latest in a string of hurtful statements the controversial pair have been hurling at each other. As MStars News reported, the reality dad left his baby mama an awful voicemail after reports surfaced that she was seeing a new guy after their breakup.

"Since you won't talk to me and you're wrong, I'm gonna leave you a voice message," Nathan began saying in an audio recording obtained by Radar Online.

"You won't talk to me because you have to talk over people when you're wrong," he attacked. "You have to start yelling... You were already talking to him when you were supposed to be on this path of being single and working towards our future and stuff like that... So, you lied... You need to grow up and take responsibility. I feel a lot better about myself because I did the right thing and you didn't."
