Ooh la la! Catelynn Lowell might have celebrated the holidays like a pro, but girlfriend didn't let all those yule logs get the best of her. This gal is just as fit n' fabulous as ever — and she recently posted a photo of herself in a brand-new outfit looking light as a feather!

Catelynn's been on a diet and fitness regime in preparation for her upcoming wedding to Tyler Baltierra, and we're so proud that she's keeping the weight off. Of course, Cate looks great at any size, but she's a major motivator for those of us who want to shed a few pounds in time for bikini season!

"I was more than 160 pounds, which is so gross!" Catelynn told Us Weekly back in June. "Now I'm 144. I only have 20 more to lose until I'm at my goal."

Looks like Catelynn has reached her goal weight and then some! Don't forget that this Teen Mom is a mere 5'2'', so her transformation is especially dramatic. Do you think Catelynn looks great at her new size? Hit the comments!
