Which Teen Mom Showed Off Her Growing Baby Bump? (PHOTO)

The 16 and Pregnant star is pregnant with baby No. 2 after giving birth to Jamie Paul Alderman, Jr. in October 2010.

The starlet controversially admitted she originally considered abortion this time around, but quickly changed her mind. Now her tummy’s growing each day, and she’s already 13 weeks along.

“13 week belly...huge. im pretty sure my placenta is growing on the outside like it did with Jr..meaning im gonna be BIG,” she tweeted today.

Oh hush, girl. You look great!
