Teen Mom power couple Catelynn Lowell and Tyler Baltierra have always secretly been our favorites since we first saw them on 16 and Pregnant many moons ago. The adorable duo has been together since the seventh grade, and although they’ve had their ups and downs, they’re now engaged and ready to start their life together!

But when we first met them in 2009, they looked completely different than they do now. Three years ago, they were just little kids, and Cate even still had braces on! Back then, babyfaced Ty spiked his hair with plenty of gel, and both of them still dressed like high schoolers. (But that was OK — they were in high school, after all!)

Now, they’re nearly unrecognizable. In the photo above (on right), they were both dressed sharply in professional attire at a speaking engagement, but they still added their own flair. Cate’s hot pink blazer and Ty’s green jacket spruce up their outfits, but they look like adults, ready to tackle the world. That’s a huge step up — especially in comparison to their 16 and Pregnant days (on left).

And on top of that, Tyler is now an aspiring actor and Cate is a slimmed-down career woman, and they’re both ready to take their next steps together. Aww!
