Chris Brown was arrested for rape earlier this week in France.
After a brief investigation, the charges were dropped and Brown was free to return to the United States.
According to his French lawyer, Raphael Chiche, Brown will sue his accuser for defamation.
"Chris Brown is free. No lawsuits were filed against him. He vigorously challenges the charges against him. A complaint for slanderous denunciation will be filed tomorrow with the public prosecutor of Paris."
The accuser, a 24-year-old model, claimed Brown raped her at his hotel room after meeting her at a Paris nightclub.
