Teen Mom cutie pie Catelynn Lowell has been on a weight loss tear!
Perhaps she's getting ready to fit into a wedding gown that will wow fiance Tyler Baltierra. Or maybe she just wants to get in shape.
Either way, she looked skinny (but healthy) in new pics she posted recently. But Catelynn isn't stopping there!
"I'm for real sooooooo tired right now! Gym kicked my butt!!" she yesterday. "But lost three more pounds!"
Look at you now, girl!
