Kris Jenner Turns 57 - See Her Before She Was Famous.

The world's hardest working "momager" has made stars of her six kids: Kourtney, Kim, Khloe and Rob Kardashian (with ex-husband Robert Kardashian), and Kendall and Kylie Jenner (with current husband Bruce Jenner).

Kris has always been open about her changing looks. She's undergone two boob jobs and had her face redone (and documented for "Keeping Up With the Kardashians") prior to Kim's 2011 wedding to Kris Humphries.
