Casey dominated U.S. headlines last year before she was acquitted of murdering her two-year-old daughter, Caylee, who went missing Orlando, Florida in July 2008.
Her six-week televised trial was described by Time magazine as 'the social media trial of the century.
She was found not guilty of murder, aggravated child abuse, and aggravated manslaughter of a child.
However, she was charged with four misdemeanour counts of providing false information to a law enforcement officer.
