'Teen Mom 2' cast member Jenelle Evans is unhappy with ex-fiance and baby dady, Nathan Griffith. The reality TV star took to twitter to lambast her ex-partner after Nathan's pal Josh Friedman accused her of starting rumours before her court date for custody. Josh tweeted, "Amazingly rumours surface the week Jenelle goes to court. Everyone look left so you don't see what's going on to the right!" reported OK! Magazine

However, it seems like Jenelle didn't take the tweet too well. She tweeted back saying that Nathan wasn't a responsible parent. Furthemore, Jenelle revealed that the baby daddy bought someone an Ipad instead of winter clothes for his son, Kraiser.

According to reports, the two have had several issues for the past month involving Jenelle's now boyfriend, David Eason, who has been abusive in the past. 

An insider said, "Nathan is absolutely worried about Jenelle dating David and him being so close to [their son] Kai[ser]. He is looking into what he can do about custody. Things are in the works. Nathan wants Kai to grow up safely and this guy doesn't seem like a good guy," reported In Touch Weekly (via Radar).

The magazine quoted a source who said that Jenelle wants her kids to spend time with Nathan, but she would rather have them meet at Nathan's mother's house. Jenelle's ex fiance, who has a daughter from a previous relationship, has a similar arrangement whenever he  wants to see her.

Jenelle and Nathan split during the filming of MTV's  reality TV show "Teen Mom 2" season 6.
