Barton was arrested on suspicion of driving under the influence, possession of marijuana, and driving without a valid license on December 27, 2007. She was stopped by the police during the early morning hours in West Hollywood, California when she was seen "straddling the lanes and failing to signal for a turn". Police discovered during the traffic stop that Barton "was an unlicensed driver and was driving while under the influence of an alcoholic beverage". She was detained and released later the same morning from the West Hollywood Sheriff Station on US$10,000 bail. On January 11, 2008, Barton called into Ryan Seacrest's radio show On Air with Ryan Seacrest (KIIS FM) and took full responsibility for her actions:

Barton was subsequently charged with two misdemeanors: driving without a valid license; and a DUI.
