Jenelle Evans has sworn off boys and says she’s broken up with Kieffer Delp once again — this time, she claims, because she found out he’s been doing drugs!

The troubled Teen Mom star went on a road trip to New Jersey with Kieffer, but she says that he was doing drugs during their “horrible” week-long trip.

Jenelle and Kieffer were meeting his family, but she claimed all they did was sit on their “a**es not doing sh*t,” in a new blog post.

“Then Kieffer of course gets this bright idea to start apartment hunting and that we should move up north. I'm from the north so I didn't have a problem with that,” Jenelle wrote.

“The problem was I would be 4-5 states away from my son AND family! by the end of the week I found outfielder had been abusing drugs the entire week we were there. When I heard that I said f**k it and called my mother to fly out to me so she can drive back with me to NC.”

As Breaking Celebrity News exclusively reported, Jenelle’s plan of moving to New York or New Jersey would seriously compromise her custody battle against her mom for her son Jace, but she says she realized this and isn’t planning to do anything to compromise her situation.

"Once coming home to my mom’s house I felt like I was at home again and best of all I was reunited with my son who before this incident I hadn't spoken to in a month," she wrote. "I will never ever put myself in that horrible situation again especially if I want my son back.”
