We couldn't be more proud of Teen Mom star Catelynn Lowell. In just a few short months, the soon-to-be Mrs. Tyler Baltierra has shed a total of 20 pounds! But how did she do it?

Good old-fashioned Weight Watchers!

"Best thing ever invented!!!" she told a fan on Twitter.

But as we all know, getting fit isn't just about monitoring your calorie intake. If you want to drop major pounds, you must also focus on cardio.

Catelynn and her fiance have been hitting the gym together, working closely with a personal trainer. You know what they say — the couple that works out together stays together!

But in all seriousness, we're super proud of our girl Catelynn and we know she'll look fantastic on her wedding day.
