Kim Kardashian freely admitted that shedding her baby weight was the greatest challenge in her life. The actress lost about 50 pounds and proudly showed it off during Jay Leno's interview. She wore a transparent white Dolce & Gabbana dress that showed her black underwear.

Though we can't say that we dig the outfit, we do applaud the reality star for standing up to criticism and changing her body for the better. During her pregnancy Kim was so bloated that people poked fun at her. She said that the criticisms really hurt her but now she's back on track! Kudos!
