Hard work pays off, y'all! Just look at Teen Mom star Catelynn Lowell. This pretty lady has struggled with her weight ever since giving birth to baby Carly back in 2009 — but not anymore! And it's all thanks to a little thing called diet and exercise.

Catelynn's proud of her success, but her biggest fan is none other than hubby-to-be Tyler Baltierra. Her main man just can't stop tweeting words of encouragement and support.

"Look at my babe @CatelynnLowell SO proud of her weight loss! My beauty, My angel, My soul mate!" he posted on January 26, along with a picture of Cate looking slender and sexy.

While we're not huge fans of her black and white ensemble, we're definitely loving her newfound confidence — the most important accessory of all. After all, you're never fully dressed without a smile!
