"Teen Mom 2" star Jenelle Evans is already sharing photos of her new baby bump -- but don't expect to see it on TV anytime soon.

The pregnant reality star posted the first photo of her growing belly on Instagram early this morning, captioning it "Baby bumpppp. My little angel !"

The 21-year-old (who doesn't have custody of first child, Jace) opened up about her new pregnancy with husband of one month, Courtland Rogers, last night with MTV.

"I missed a few birth control pills, and found out I was pregnant at a doctor’s appointment. I was really surprised,” Evans says.

"I know a lot of people will say we’re not ready, or judge me from my past. I want to prove to everyone that I can do this,” Jenelle added. “This wasn’t planned, but it happened so we’re taking it as we go. Courtland and I are happy and excited now. We have our own place, we’re married, and we’re both working. We know having a child can be difficult, but we’re going to do our best."

And while some of the drama could unfold on a fourth season of "Teen Mom 2" (if MTV greenlights one), MTV says there is definitely not a spinoff for the couple being planned.

"We can report that it's not true and there is no new show in the works for the newlyweds," the network said in a statement.

This is the first child for Jenelle and Courtland, who both have children from previous relationships.
