The supermodel was arrested on Friday night in Greenwich, CT. According to Connecticut State Police, Stephanie was stopped on an off-ramp from I-95 when another car came up and stopped behind her. Instead of going forward ... cops say Stephanie threw her 2015 Range Rover into reverse and hit the other vehicle.
She refused to take a field sobriety test, even though the officer on the scene said she smelled like booze, was unsteady on her feet and had bloodshot eyes.
The driver of the other car did not report any injuries.
