Let's hope she's a better mom this time around!

Teen Mom star Jenelle Evans is pregnant with her second child, and now she's showing off the beginnings of her baby belly on Twitter!

"Baby bumpppp. My little angel," she captioned the snapshot.

Although the pregnancy wasn't planned, the 21-year-old told MTV she understands why people will have a negative reaction to the news and wants to prove them wrong.

"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. 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," she said.

The newly married reality star's son Jace, from a previous relationship, lives with her mother Barbara.

Let's hope she sticks to her word!
