Jenelle Evans Slams 'Fake' Leah Messer Amid Explosive 'Teen Mom 2' Cast Feud

Jenelle Evans went off on enemies Chelsea Houska and Kailyn Lowry last week – and now she's going after Leah Messer! RadarOnline.com can reveal exclusive details on the explosive Teen Mom 2 feud that's rocking the franchise.

The latest drama started when Messer discussed Evans' husband David Eason pulling out a knife at the Teen Mom 2 reunion in October. "My friend who went with me was terrified," Messer said on Lowry and Lindsie Chrisey's podcast Coffee Convos, obtained by The Ashley's Reality Roundup. "She was right there and she thought one of the producers was going to get stabbed in the face, which is not OK! I don't even remember if it was because they were not serving any more alcohol or… but we were there for work! I mean, you can have a few drinks socially but, it's not that appropriate."

When Evans saw her quotes, she fired back, "Hey @TM2LeahDawn, last time I recalled the kids weren't at the New Years party we were 'working at.' Stop being so dramatic. My name or my husband's should never come out of your mouth, but for a podcast and ratings?! Of course. #Fake."

But she didn't stop there, as she also slammed Lowry. "Kail uses anyone she can to gain whatever she can… remember that," she tweeted, adding, "Why is my life your everyday topic for your show? Maybe I should be the one with a show then."

Last week a fan told Evans, "You just wish you were Chelsea… You know cause she's cool and normal and a good mom with a normal dude." She fired back, "I rather not be boring as f**k, thanks."

A source close to the cast exclusively told RadarOnline.com what started the feud. "It started during press and promoting the new season a few years ago when Chelsea and Kail posted some photos together," the insider said. "Jenelle got jealous over it. Jenelle left early to go to do her own thing at a club appearance and wasn't even there. She called them snakes in the grass and threw a big hissy fit."
