Teen Mom 3's Mackenzie Douthit is blowing our minds with her insane post-baby body. We've said it once and we've said it again, home girl is basically the eighth wonder of the world.

We have no idea how she's managed to bounce back from pregnancy so quickly! This girl gained a fair amount of weight when she was baking baby Jaxie in her lady oven, and since giving birth back in February (only four months ago), she's dropped crazy poundage.

Mackenzie recently revealed that she's actually a few pounds less now than she was before her pregnancy, and she recently took to Twitter to announce that she no longer weighs over 100 on the scale. "Finally back to two numbers on the scale," she tweeted on May 29.

We don't know how she does it. Actually, we kinda do. Since she is a diabetic, Mackenzie eats a super-healthy diet full of vegetables. On top of that, she's addicted to working out, and recently got back into her passion, professional cheerleading and stunting. Girlfriend is burning more calories than she eats!

And before you start clutching your pearls at Mackenzie's dramatic weight loss, fear not — she looks amazing and healthy, as is evident in a recent bikini pic of herself and her hubby, Josh McKee.

By the way, Mackenzie's weight loss is the latest in a string of Teen Mom body transformation stories. 16 and Pregnant's Danielle Cunningham recently dropped a whopping 90 pounds, and Teen Mom 2's Kailyn Lowry has been steadily shedding her baby weight since giving birth back in November!

Do you think Mackenzie looks good at her current weight? Weigh in (LOL, get it?) below!
