Kristin Cavallari shot to fame on the MTV reality show Laguna Beach: The Real Orange County in 2004. The Cali girl's on-going feud with Lauren Conrad over Stephen Colletti drove the plot of the first season and turned all three into stars. Kristen became the show's narrator in the following season before leaving the show in 2006 to pursue acting. After a few short acting gigs on Veronica Mars, Get This Party Started and CSI: NY, Kristin returned to reality TV in 2009 when she joined the cast of The Hills. In 2011, footballer Jay Cutler proposed to Kristen before the engagement was called off three months later. The blonde beauty then signed up for Dancing with the Stars and was partnered with expert Mark Ballas.
