Lindsay Lohan has spoken out over her recent arrest, insisting she's innocent.

The Mean Girls actress was booked after police pulled her over after a car chase involving the mum of her aide who'd recently quit.

She was taken into custody after failing a field sobriety test while cocaine was found on her during a subsequent search, according to police.

But Lindsay said: "I'm innocent... I did not do drugs, they're not mine. I was almost hit by my assistant Tarin's mom. I appreciate everyone giving me my privacy."

The 21-year-old was charged with driving under the influence, driving on a suspended licence and possessing cocaine.

She is due in court next month for an earlier charge of driving under the influence in January.
