Kristin Cavallari (Seasons 5-6)
Then: When LC decided to bail on reality TV, Kristin did what she does best — she replaced her. She was quick to stir up drama by making a play for Audrina’s man, Justin Bobby, and she later sparked a fake romance with Brody Jenner.
Now: Kristin was a contestant on Season 13 of Dancing With the Stars, but she was eliminated in week three. She got engaged to Chicago Bears quarterback Jay Cutler in April 2011, only to call it off three months later. Kristin confirmed that they were back together and engaged again in November 2011.
Then the former bad girl shocked us all in January 2012 when she revealed that she’s expecting her first child with Jay. Camden Jack Cutler was born on August 8, 2012.
