And for biggest transformation of a reality TV star ... the award should definitely go to Snooki. I can't think of any other celebrity in recent time who has undergone such a metamorphosis, or at least a positive one anyway.
From her Jersey Shore days falling down and peeing on herself to becoming an admirable mother, she's really made changes for the better in her life. Now, on top of it all, she has also completely changed her body, losing an amazing 42 pounds since giving birth to her son, Lorenzo, last August.
She's rocking a bikini on the cover of Us Weekly, and she has never looked better. At just 4-foot-9, the famous Guidette now weighs 102 pounds. That puts her BMI at a healthy 22.1, and it's clearly a weight that suits her. Who would have ever thought Snooki would be an inspiration in so many ways?
So, of course, now what we all want to know is: How did she do it?
