UPDATE 9/6/2013 4:05 p.m. ET: TMZ reports that Kristin was stopped for speeding this morning and given a $120 citation for living in the state and driving without a valid Illinois license. A rep for the Evanston Police Department said Kristin will need to get a valid Illinois driver's license if she wants to continue driving in the state. 

ORIGINAL STORY 9/6/2013 2:06 p.m. ET: Motherhood may have matured reality star Kristin Cavallari, but today the former Hills star tweeted about having to post bail in Illinois, where she currently resides with husband Jay Cutler.

“Who knew having a California drivers license in Illinois was a CRIME to be escorted to the police station to post bail?!! What a morning,” she tweeted on September 6.

Kristin and Jay moved into their lavish Chicago home this summer after tying the knot in June. Despite having a permanent address in the Windy City, K. Cav claims she had every right to hold a California license.

“FYI...I still have an apartment in LA so I'm a resident of California,” she tweeted.

Who knows, maybe her license was dunzo and the cops weren’t having it. An arrest and posting bail seems to be a bit much for a simple driver's licence mix up, but we all know how much the former wild child hates the cops from her Laguna Beach days.
