VIDEO: Is Teen Mom's Tyler Getting Ready To Pop The Question?

Tyler may have a lot of doubts, fears and uncertainties in his life, but when it comes to Catelynn, he knows exactly how he feels. Together, they've endured a pregnancy, labor, adoption and more than their fair share of family drama, all of which has helped to reinforce what Tyler already knew: Catelynn is -- and always will be -- The One.

Now, since actions speak leader than words, Tyler's decided to show his girlfriend just how much he loves her -- by buying a ring(!) and letting her know she's the one he wants to spend the rest of his life with. Watch Tyler tell his mom how serious he is about "solidifying" things with Catelynn and tune in tomorrow night to see how it all goes down on Teen Mom.
