Britney Spears DUI arrest video

Newly surfaced dashcam footage and police reports from Britney Spears' March DUI arrest show the pop star fumbling through a roadside sobriety test.

Spears reportedly spoke 'nonsensically' and displayed 'drastic mood swings' during the encounter with California Highway Patrol.

The video shows the singer being handcuffed after failing field tests, during which she allegedly offered officers lasagne and a swim at her home.

Spears eventually pleaded guilty to reckless driving and was sentenced to a year of probation.
