Is Farrah Abraham about to become a teen mother for the second time?

No way!

The Teen Mom star, 19, is slamming a new OK! magazine cover claiming that she's pregnant again. (Sophia, her daughter with late beau Derek Underwood, is now 19 months old.)

"No, I am not [pregnant]," Abraham tells MTV's Remote Control. She adds: "I don't understand where it comes from because I don't have sex!"

The culinary student and part-time waitress explains: "I don't have time to date. I'm just not ready to be intimate with someone. It's a time in my life where I'm just kind of shut down."

"I definitely would not put myself in that situation again," the single mom adds of unexpected pregnancy. "I am very knowledgeable about what to do for my life and how to be a good mother, and how to use precautions if I do have sex."

"I'm just being responsible," Abraham says of her quiet home life. "It's where I'm supposed to be right now."
