Jeremy apparently decided to propose to his girl with a 1.5 carat princess-cut diamond on Christmas Day, but claims he was surprised with the baby news. This is another unplanned baby coming into the world with two irresponsible parents.

Leah’s fiancé said, “Yes, Leah is having my baby! I was at work when Leah called to tell me. She’d gotten blood work done and it came back positive. At first I was kind of surprised — but I was happy.”

The 19 year-old Teen Mom seems to be pretty excited with the news. A bigger family, more mouths to feed and give a proper education. What’s not to be excited about?! Leah actually believes she finally found her prince charming in her new fiancé.

“We have a really good connection,” she gushed. “It’s different from Corey and my relationship, because we were kinda like forcing it… With Jeremy, you know when you’re supposed to be with somebody and you’re not.”
