"She came back here from California telling me she was pregnant with my child and I said this is impossible, you've been in California two months and back here for only a week," the 19-year-old Las Vegas resident told the Post.
"After I told her that's not my kid, you've only been here for a week, then she told me, 'No, I got pregnant before I left by you," Terranova continued. "But it didn't make sense because she had a doctor's note saying she wasn't pregnant enough for that to be possible. It didn't add up."
