Kristin Cavallari was forced to post bail on Friday.

But don't get the wrong idea: The former "Hills" star was not arrested.

However, the 26-year-old, who lives part of the year in the Chicago area with her husband, Chicago Bearsquarterback Jay Cutler, did find herself in legal hot water when police stopped her for speeding as she drove into the suburb of Evanston at 11:50 a.m. Friday.

Cavallari was able to produce only a California driver's license, which was not good enough. Illinois requires that drivers who move there from other states transfer their driver's license in the first 30 days in the Land of Lincoln, according to the Chicago Tribune.

The California girl officially moved to Chicagoland in early 2012. In July, it was revealed that the couple and their 1-year-old son Camden reside in a luxe $10,000-a-month rental home in nearby Winnetka, Illinois, when they're in the Midwest.

Unfortunately for Cavallari, California is not one of the states that participates in a cooperative agreement with others regarding licensing. She was told to follow the officer who stopped her to the police station and post $150 bond. Her ticket also comes with a $120 fine.
