Stephanie Seymour was arrested for a DUI Friday night in Greenwich, CT, according to TMZ.
The gossip site reports that the supermodel was stopped on an off-ramp from I-95 when another car stopped behind her.
Instead of driving forward, Seymour reportedly put her car into reverse and hit the car behind her.
TMZ reports that she appeared unsteady on her feet and smelled of alcohol but refused to take a field sobriety test.
A rep for the 47-year-old did not immediately return FOX411's request for comment.
