Tennessee Titans wide receiver Kenny Britt has been arrested ... again ... this time for driving under the influence in Kentucky ... TMZ has learned.
The NFL star was taken into custody by the Fort Campbell Police Department at 3:30 AM Tuesday while attempting to drive on to Fort Campbell -- a U.S. Army base located on the border of Kentucky and Tennessee.
We're told Britt was with a soldier at the time of the arrest.
Britt's cherry red 2008 Dodge Challenger was taken to a nearby impound lot (pictured below).
It DEFINITELY ain't Kenny's first brush with the law ... the 23-year-old was busted back in April 2011 for careless driving ... and in June 2011, he was popped in New Jersey for resisting arrest.
A rep for Fort Campbell tells TMZ the incident is "under investigation."
11:45AM PT -- MPs tell us Britt refused a breathalyzer test, and has been charged with DUI. He was released, and escorted off the base.
