Jay Cutler spent time in a Tennessee jail Thursday after he was busted for driving while intoxicated ... TMZ has learned.
The former NFL star and ex-husband of Kristin Cavallari was arrested for DUI on Thursday evening in the city of Franklin, TN.
Cutler was then booked into the Williamson County Jail, where he posed for a scruffy mugshot -- and, as you can see, the dude doesn't look too happy.
