Scott Disick Cheated On Kourtney Kardashian With Kristin Cavallari

OMG!!! Is Scott Disick hooking up with Kristin Cavallari again? Cavallari was close with Kourtney and Scott when she dated Kourtney’s step brother Brody Jenner during her Laguna Beach days. Kardashian’s friend says the two have been on dates before and that they hooked up in February 2009 in Las Vegas. Kourtney was pregnant and they were on a break at the time. Rob and Kristin are in DWTS together this season and Kourtney has banned Scott from going to the show tapings. The Kardashian sisters even have a name for Kristin “whore bag.”

Sounds like Kristin is trying to keep it in the family, is Rob next? -StarzUncut
